Variable DC Power Supply 0.5 KW

Customer requirements are shown below:

• Non-Motorized Variable Transformer Controlled Power Supply, P/N 6-2C-18407PS
• Input: 120 VAC, 1 PH, 60 Hz
• Output: 0 to 750 VDC, 0.5 Amp max
• C1 and C2 reduce ripple to 4 V p-p at maximum output voltage
• Input and output have fuse protection
• Bleeder resistor R1 provides output capacitor discharge
• Variac knob manually adjusts output from 0 to 750 VDC
• Voltmeter and ammeter monitor output voltage and current
• The unit is used to charge the capacitors periodically to increase shelf life.

The schematic diagram is shown below:

This unit is used to charge up the capacitors on a periodic basis when they have been in the inventory for a long period of time. The capacitors require a recharge to increase shelf life. The photos of the unit are shown below:
