Pulse current and the Taylor HVPS

[Paul Andrews]

Hi,

I'm just doing some planning for a small battery powered clock using ZM5900 tubes. I want to drive 6 of them and was looking at the Taylor 1363/1364 HVPS units. The datasheet for the tubes states a current in the range 1-2mA, which is well within the capabilities of the Taylor HVPS, but also a pulse current of 10mA. What is a pulse current, and does this actually affect my plan to use this power supply?

Hi Paul,

"Pulse Current" usually refers to a much higher current
which can be gotten away with for a very short duration.
This scheme is typically used in multiplexed displays
which have any one tube turned on very briefly, before scanning
to the next tube and pulsing it.

For your application, you will be using the normal and much
lower current value specified in the tube data sheet.

I have one of those John Taylor 1364 power supplies.
It works perfectly, you will be very pleased with it!

Chuck
