Ringing voltage output

CX 2000 power supply module: 86 V AC, -48 V DC

Description   

A 19" w x 5.25" h rack mount chassis containing four separate modules, each rated for 2.2 A (DC) and 0.1 7 A (DC) output current. The modules operate in a parallel mode output current.

Input power

90-132/180-264 V AC 47-63 Hz automatic range selection.

DC output

24V DC/ 30 V DC and -48 V DC @ 2.2 A/module total.

DC output regulation

Less than 1%.

DC output ripple

Less than 0.5% peak to peak.

Output isolation

24 V DC and -48 V DC isolated from chassis ground. AC output is referenced by -48 V DC output.

AC output

0.17A/module with 100% duty cycle.

AC output frequency

17, 20, 25, or 50 Hz +/-1 0% switch selectable.

AC output regulation

Less than 10% for the full input voltage range and no load to full load. 90 V AC maximum.

AC output wave form

Simulated sine wave with less than 20% distortion.

Current limiting

All outputs have current limiting with full protection and auto recovery.

Output indicator

Green LED on the module indicates that all outputs are operating. External signal indicates an alarm condition.

Module failure protection

A failure in any module results in its outputs being automatically taken offline.

Temperature range

Ambient temperature range is 0 to 50 degrees C for full load operation.

EMI design standards

Approved to FCC 20780, Part 15, Class B, EN55022, Class B, and EN50082-1.

Safety design standards

Approved to EN60950, UL1950 3rd edition and 1/24/00 CSA C22.2-950.
