Electrical Specification
|
|
Input voltage (at ground potential):
|
24V d.c. ±0.5V at 3A maximum.
|
|
Output current:
|
0.8A to 5A at up to +7.5 volt d.c.
|
|
Control:
|
0 to +10V gives 0 to 5A, or by internal or external potentiometer
|
|
Ripple:
|
Less than 200 mV peak to peak, ripple frequency 50 kHz.
|
|
Load regulation:
|
Less than 1% for 10% change in filament resistance. The output
impedance of the power supply is electronically controlled
to maintain the filament temperature as the filament changes
|
|
Line regulation:
|
Less than 1% for 0.5V change in 24V.
|
|
Temperature co-efficient:
|
0.1% per °C.
|
|
Current monitor (pin 3):
|
0 to 10V represents 0 to 5A (accuracy ±5 %, source resistance
10 kohm).
|
|
Inhibit (pin 8):
|
Low = on, high or O/C = off.
|
|
Operating temperature:
|
0 °C to +45 °C.
