Output
VA 100 VA
Thermal Limiting Output VA may be reduced by reducing Vac when
operating simultaneously above 50°C and less than
-50Vdc input.
Vac is reduced only sufficiently to prevent damage to the
ringer.
Load Power Factor Operating: 0.5 Leading to 0.9 Lagging
No Damage: 0 Leading to 0.7 Lagging
Operating Temperature -40 to +75 °C See Output VA Thermal Limiting.
Heat Dissipation 50 W (170 BTU / hr)
Under Voltage Shutdown 50% of Output Vac Set Point
While shutdown due to external fault, restart will be
performed at approximately 2 minute intervals.
