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. |
| ISOLATION TO: |
5 kV (K1/60), 30kV (K1/104) & 50kV (K1/95). |
| CONTROL (AT GROUND POTENTIAL): |
0 to +10V gives 0 to 5A. (Internal & external potentiometer control also fitted). |
| 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 ages |
| LINE REGULATION: |
Less than 1% for 0.5V change in 24V. |
| TEMPERATURE COEFFICIENT: |
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. |
