The PSC-100 series is supplied with full alarm signals including AC OK and battery low alarm and can be driven by any external DC voltage from 4 volts up to 50 volts with a 30mA maximum load. If the main power source is interrupted the PSC-100 switches to battery backup mode, a TTL signal will be sent out to a monitoring unit to warn of impending unit failure.
If the battery voltage goes down to 11V (for 12V battery bank) or 22V (for 24V battery bank), another TTL alarm signal will be sent out to warn of the ”battery low” situation. The battery backup loop will be cut off when the battery voltage goes down to 10.5V or 21V to prevent batteries from over-discharging.
The Mean Well PSC-100 series can operate up to 70ºC of high ambient temperature with only free air convection. Protection for PSC-100 includes short circuit, overload, and over voltage protection for the output side. Battery polarity protection (by fuse) and battery low cut-off for the battery side.
The Mean Well PSC-100 series is supplied with worldwide safety certificates, UL, CUL, TUV, CE, and CB. Applications include the fast growing security industry, emergency lighting systems, UPS systems, central monitoring systems and automatic door systems.
