DC INPUT: | -48VDC nominal. Full output over -42VDC to -58 VDC input range. |
AC OUTPUT: | 93VAC @ 0.10A under normal conditions. Peak loading to 0.12A permitted for short duration. |
AC OUTPUT REGULATION: | Total line and load regulation is less than 10% for the full DC input range and from no load to full load. |
OUTPUT ISOLATION: | The AC output is referenced to the -48VDC input. |
AC OUTPUT FREQUENCY: | 20Hz +/- 1Hz is standard. 30 Hz and other frequencies available. |
AC OUTPUT WAVEFORM: | Simulated sine wave with less than 20% distortion. |
ZERO CROSSING SIGNAL: | An optocoupler isolated open collector NPN transistor is turned on for approximately 2 milliseconds at every zero crossing of output voltage. This transistor will control 5mA @ 20VDC. The signal is used to phase control the ringer loads allowing triple capacity. |
CURRENT LIMITING: | Output has current limiting with full protection and automatic recovery. |
OUTPUT INDICATION: | An open collector NPN transistor is turned on whenever the AC output is properly operating with -48VDC bias. This transistor will control 5mA @ 20VDC and is optocoupler isolated. |
TEMPERATURE RANGE: | Ambient temperature range is 0 to 50 degrees C for full load operation. |
MOUNTING: | Standard model has been designed for installation on a mother board. A substitute connector (Optional Features) permits input/output via a cable connector and mounting on any surface. |
CONSTRUCTION: | PC board assembly and cover 2.5" x 4.8" with maximum overall height of 0.70". |
WEIGHT: | 5 oz. |
SAFETY STANDARDS: | Compliance with IEC 950, UL 1950 and CSA C22.2-950. |
