This module operates from a continuous voltage of around 15 volts and provides precise heating for a wide variety of regulated DC voltage tubes.
Two distinct outputs are available:
A low voltage, high current adjustable output from 1.2V to 13V for heating common tubes.
A "high" voltage adjustable output from 13V to 60V for heating all tubes.
These outputs can be selected by a switch, with 0V as the common ground.
Nominal input voltage: 15V DC
No-load input current: 0.1A
Maximum input current: 3A
Output voltage 1: Adjustable from 1.2V to 13V using P1
Output current 1: 2.5A to 5A depending on voltage (5.5A at 4V, 2.5A at 12.6V)
Output voltage 2: Adjustable from 13V to 60V using P2
Output current 2: 0.12A to 1.2A depending on voltage (1.2A at 15V, 0.12A at 60V)
Voltage regulation: Better than 2%
Dimensions: 95 x 85 x h = 48
A 15V - 3A power supply module and a 3-digit voltmeter for displaying the output voltage are available upon request. Please contact me for details.
