Controls & Indicators
The front-panel controls and indicators of the B & K Precision Model 1602 High Voltage Power Supply include:
1. Current Meter: Measures actual B+ output load current during normal operation and indicates B+ current limit when the set/reset switch is pushed.
2. B+ Current Set: Provides adjustment of B+ current limit, continuously adjustable from 10-200mA output current.
3. B+ Current Push to Set and Reset (Set/Reset) Button: When fully depressed and held, connects the current meter to read the B+ current limit setting. When pressed and released, resets B+ overload circuit if it has been tripped.
4. Overload Indicator (Red): Lights when B+ current limit has been exceeded and the B+ supply has shut down.
5. STBY ON: STBY position removes power from terminals and voltmeter but leaves the DC supplies activated and at standby condition. ON position applies power to output terminals and voltmeter.
6. Power: Lights continuously when the power supply is turned on.
7. Terminal: Earth and chassis ground terminal.
8. + Terminal: Positive polarity of B+ output.
9. – Terminal: Negative polarity of B+ output.
10. Voltmeter: Indicates output voltage of B+ or C- supplies.
11. Meter Range: B+/G400 position selects full scale range of 400 volts for voltmeter to meter B+ output voltage. C-/G100 position selects full scale range of 100 volts for voltmeter to meter C- output voltage.
12. Level (B+): Turns off power supply at extreme counterclockwise rotation. Clockwise rotation turns on power supply and adjusts B+ output voltage upwards.
13. – Terminal: Negative polarity output of C- supply.
14. + Terminal: Positive polarity output of C- supply.
15. C- Control: Adjusts C- output voltage between terminals from 0 to -100V with clockwise rotation. Output voltage is monitored on voltmeter when meter range switch is in C-/G100V position.
16. & 17. 6.3VAC Terminals: 6.3VAC output terminals protected by breaker.
18. 12.6VAC Terminals: 12.6VAC output terminals protected by breaker.
19. AC Reset: Circuit breaker in series with terminal protects against excessive overloads between terminals.
