Power Supply (HP E3630A)
Used in the following activities:
This is a constant-voltage/current-limiting triple output power supply that combines two 0 to ±20 V tracking outputs rated at 0.5 amps with an additional single output that is rated at 0 to 6 volts and 2.5 amps.
- Turn line switch to ON position.
- Push + 6 V meter switch and vary + 6 V voltage control. At no load current should be 0.
- Repeat process for + 20 and - 20 volt outputs.
- Outputs are from their respective terminals with reference to COM.
- Voltage and current are displayed at the LED module.
Specifications
| DC Output and Overload Protection | 0 to ±20 V Outputs: Maximum rated output current is 0.5 A. Short circuit output current is 0.55 A ±5 % | 0 to + 6 v Output: Maximum rated output current is 2.5 A at 6 V. A current foldback circuit limits the output to 2.75 A ±5 % at 6 volts. |
|---|---|---|
| Tracking Accuracy | The + 20 and - 20 V outputs track within 1 % with the tracking ratio control in the fixed position. | |
| Load Regulation | Less than 0.01 % plus 2 mV for a full load to no load change in output current. | |
| Line regulation | Les than 0.01 % plus 2 mV for any line voltage change within rating. | |
| Pard (Ripple and Noise) | Less than 0.35 mV rms/1.5 mV p-p ( 20 Hz - 20 MHz). | |
| Meter Accuracy | ±0.5 % + 2 counts at 25°C ±5°C | |
| Meter Resolution | Voltage:10 mV Current:10 mA |
Note: There are more of these units in the upper year labs, purchased courtesy of a grant from Nortel.
