Adjustable High Voltage Power Supply Converter

Features:

    Converter-regulator module
    Module dimensions: 85 x 55 x max. 25 mm
    1 input of 6 to 9 V DC or AC (batteries or transformer)
    2 outputs: 1 adjustable regulated high voltage power supply of +30 to +300 V 1 negative power supply of -24 V
    High voltage supply capacity (examples): 25 mA at 80 V with a 9 V input to the module (15 mA with 6 V) 20 mA at 200 V with a 9 V input to the module (10 mA with 6 V)
    Negative power supply capacity (bias source): 4.5 mA at -24 V with a 9 V input to the module (2.5 mA with 6 V)
    No-load primary current: 50 mA from 6 to 9 V
    High voltage regulation: better than 3%
    Short circuit protection

Composition:

    1 ready-to-use module
    1 principle and connection diagram

Use:

    Converter-regulator module for battery-powered receiver supplies, circuit testing, capacitor regeneration, portable high voltage power supply, etc.
    Converter providing 2 sources of energy for different tests or power supplies (battery-powered receivers, old radios, tubes, Geiger-Müller counters, etc.)

1 adjustable "High voltage" power supply using a potentiometer to set the voltage between 30 and 300 V DC with a current capacity sufficient for most applications. This voltage range can be changed from 0 to 450 V by replacing 2 resistors and 1 external potentiometer that can be wired in place of the adjustable 10-turn potentiometer on the card. 1 digital control input of 0 / +5 V that can also be used to turn on or off this power supply.

1 negative power supply stabilized by a Zener diode, delivering a fixed voltage of -24 V; this voltage can be adjusted to other values between 0 and -40 V by changing the Zener diode.
