495 Power Supply

Adds +6 V or –6 V to existing NIM bin
6-A output
Adjustable from 5 to 6 volts
Over-voltage crowbar protection
Foldback current limiting

The ORTEC Model 495 Power Supply is a single-width NIM module that adds 6 V to existing NIM-bin/power supply combinations. The Model 495 takes power from the 117 V ac bus on the bin and energizes either the +6 V or –6 V bus, depending on the internal polarity selection. Front-panel LEDs indicate which output polarity is active. The Model 495 is factory shipped in the +6 V output condition. In the event the Model 495 is inserted into a bin that already has ±6 V outputs, no damage will occur to any instrument. The Model 495 will indicate the presence of both outputs on the front panel.

Designed for reliable service life, the Model 495 uses only high-quality components. State-of-the-art switching conversion circuits give the Model 495 high efficiency and cool operating temperatures, and the input and output circuits are filtered for very low noise.

Protection circuits include an input line fuse and filter, an output over-voltage crowbar, and foldback current limiting. Polarity selection is accomplished by printed wiring board (PWB) jumpers without the need for special keys or tools.
