Viking Industrial Products' (VIP) open-frame RP30 RingMaster series of ringer power supplies is a PC-compatible plug-in ringer supply module designed to power a multichannel analog telephone interface board. Occupying a single PC-ISA slot, it provides -48Vdc at 400mA and 93Vac at 50mA from the input power provided from the host computer (maximum loading 5V at 5A and 12V at 2.5A) to accommodate up to 16 phones.

Supply specifications include a dc output regulation of <1 percent and dc output ripple of <1 percent peak-to-peak. The ac output waveform is a simulated sine wave (20Hz, 110 percent is standard).

Options include 17, 20, 25 and 50Hz to comply with international requirements, with <20 percent distortion. All outputs have current limiting. A green LED indicates that all outputs are operating. The output connector is a Molex 70553-0040.

Operating range is 00C to 500C for full-load operation.

The RingMaster starts at $94 each in 1,000-piece quantities.
