Application: Shake or stir well before using. Apply two coats using either a brush, roller or pump sprayer allowing at least 20 minutes drying time between coats. Allow 48 hours of cure time before applying a quality paint.
General: Do not apply this product if the surface temperatures are below 50F. Store in a cool, dry place, protected from freezing or temperatures above 100F. For long-lasting protection of iron surfaces, the cured rust converter coating should be sealed with two coats of high-quality oil-based paint. No other primer is required.
Worldwide Power
The Ultra HF will automatically connect to any marina power source worldwide and provide clean, stable and reliable power for the yacht. Fully compatible with all types of marina breakers and complying with marine shore power supply regulations, having an Ultra HF on board makes the yacht a truly global vessel.
Advanced Power Design
The Ultra HF frequency converter utilizes state-of-the-art technology including the latest in power semiconductors and transformer technology, all controlled by a ultra-high speed digital signal processing control system to produce an absolutely pure output sine wave.
Reliable Power
The onboard guests do not want to be aggravated by flickering lights, black-outs and generator starts caused by fluctuations in the marina power. Regardless of the dock power supply quality the Ultra HF will always produce stable and reliable power. This reliability is achieved by manufacturing the marine power converter using only the highest quality components and by engineering the converter for actual marine use.
Maximize Marina Power
Many yachts have to reduce their air conditioning and galley loads when in the marina to prevent overloading the circuit breaker on the dock and losing all power. By conditioning and balancing the currents in the shore cord, the Ultra HF converter increases the amount of available power from the marina power system by as much as 35%. The Ultra HF is able to operate into a 100% imbalanced load while maintaining the precise regulation of all the output phases.
Marine Engineered
Designed from the ground up, based on years of marine experience, the converter is packaged in a lightweight aluminum enclosure and is engineered to operate in the worst marine conditions such as high ambient temperature and humidity. It has been extensively tested to ensure that when loads such as large motors and compressors start there are no fluctuations of the output power.

Yes! The converter allows you to transfer files from any Windows / Mac / Chrome / Linux operating system. Whether you have an old Mac and are transferring to a new Windows OS, or you have an old Linux OS and are transferring to a new Macbook OS.
As long as the hard drive itself is in good working condition, with no damage to it, you'll be able to extract your files easily. The computer does not need to work for the converter to retrieve your files.
The RLH Ultra PoE++ Ethernet Media Converter is a rugged, full featured media converter. It converts copper Ethernet to fiber, and may be used to extend a copper Ethernet network up to 62 miles (100km) over fiber optic cable.
The integrated PoE++ power over Ethernet feature provides up to 90 Watts of power to a single end device and follows the IEEE 802.3bt standard. The integrated PoE Remote Reset (PRR) feature allows this device to reset a PoE powered device on Fiber Link failure. When the fiber is disconnected on the local device it will cause the PoE output power to drop at the remote device when the PRR feature is enabled.
This system is designed to transport critical communications where reliability is paramount. It is environmentally hardened to operate over a wide temperature range and is standards compliant ensuring compatibility with existing network devices.

Traditionally, these polarization-conversion devices have been designed using birefringent materials such as liquid crystals and quartz that in essence require relatively large thickness but provide a narrow-band performance. Recently, the design of polarization converters is based more on two-dimensional (2D) structures called metasurfaces. These metasurfaces contain a periodic array of sub-wavelength resonant structures. The phase of an incident terahertz wave can be desirably controlled by those resonators to yield polarization conversion in wideband. Moreover, due to their low profile, usually
In this work, we present a free-standing three-layer transmissive polarization converter that can efficiently rotate a linearly polarized terahertz wave by 90. To enhance the bandwidth, we include two resonators, a split-ring resonator (SRR) and an H-shaped resonator, in the middle layer. Moreover, a low-loss dielectric, cyclic olefin copolymer (COC), is employed as the dielectric support and spacers. Although by far less lossy than most polymers, the COC usage in multi-layer terahertz devices has not widely been embraced since the normal spin-on fabrication technique was not successful. For the first time, we employ an unconventional fabrication technique involving multiple polymer bonding and photolithography steps to realize the three-layer polarization converter with the COC dielectric. The spectral responses of the fabricated device are experimentally validated with terahertz time-domain spectroscopy and the vector network analyzer.
The transmissive polarization converter design proposed here is made up of three metallic layers in a multi-layer structure similar to that proposed by Grady et al.11 and also demonstrated by Chang et al.26 Herein, the cyclic olefin copolymer is employed as the dielectric spacer, and a SRR and an H-shaped resonator are combined in the middle layer. A three-dimensional (3D) view for one unit of the proposed polarization converter is shown in Fig. 1(a), while the corresponding two-dimensional (2D) view of the three different layers labeled A, B, and C is shown in Fig. 1(b). The unit cell is a square of side p = 154 μm. The top and bottom layers are made of gold (Au) wire gratings of width n = 8 μm and separation m = 6 μm, placed orthogonally to each other. The separation between the middle layer and each grating, t, is 74 μm. All other dimensions are given in the caption of Fig. 1. To realize a free-standing device, the bottom grating is supported by a 3 μm layer of COC. The thickness of all metallic (gold, Au) layers is 200 nm.
In the polarization conversion process, a linearly polarized electromagnetic wave, in the y-direction, Ey, is normally incident on C [Fig. 1(b)]. The incident wave resonates with the middle-layer resonators, B [Fig. 1(b)], at multiple frequencies. The propagating waves undergo multiple internal reflections in dielectric layers. A transmitted electromagnetic wave with a strong cross-polarization transmission coefficient (txy), linearly polarized in the x-direction, Ex, is obtained at the other end. Ideally, there should be no co-polarization transmission coefficient, txx, in the y-direction. Thus, the device is capable of efficiently converting an incident linearly polarized wave to its orthogonal counterpart.
The proposed polarization converter is designed by numerically evaluating the spectral response of plausible middle-layer resonators using 3D finite-element full-wave simulations conducted with the frequency-domain solver in CST Microwave Studio. The main idea is the inclusion of multiple resonators in the middle layer to introduce multiple resonances. In our simulation, Floquet boundary conditions are employed in the x- and y-directions of the unit cell. The frequency-dependent surface impedance that accounts for the Ohmic losses27 of Au is used for all metallic layers. The COC is modeled with a relative permittivity and loss tangent (tan δ) of 2.324 and 0.0007, respectively, similar to values reported in the literature.28,29 The simulation results are compared with the experimental results in the Results and discussions section.

For experimental validation, two different setups are utilized. First, fiber-coupled terahertz time-domain spectrometer (TERA K15) is used. The experimental setup is shown in Fig. 5. In this measurement, lenses with a focal length of 5 cm are used to collimate and focus the terahertz beam onto the sample. A vertically (y)-polarized focused beam of approximately 1 mm in diameter at 0.5 THz illuminates the sample at normal incidence. The transmitted beam is then refocused into the linearly polarized detector, which can be reconfigured for either vertically (y)- or horizontally (x)-polarized waves. The co-polarization measurement is conducted as vertical in and vertical out, and the cross-polarization measurement is conducted as vertical in and horizontal out. The bandwidth of the system is >4 THz, with >75 dB dynamic range. All the measured results are normalized to a co-polarized free-space transmission, i.e., with the sample removed.
