DESCRIPTION
The SC series is designed to auto-charge and maintain Gelled electrolyte (Gel-Cell) and liquid electrolyte lead-acid batteries.
The SC series is a constant current monitoring charger for the charge and maintenance of fixed location UPS, emergency lighting
systems, and telecommunications battery backup systems. The charger is protected against over loading by deep discharge start
circuitry with auto shut down due to over-voltage, over-temperature, short circuit and reverse polarity. Switch mode circuit design
provides high efficiency, compact size, cool operation and high reliability. Dual color red/green LED provides a visual indication of
charger status.

Since individual applications are subject to great variation, DuraComm makes no representation or warranty as to the merchantability, suitability or fitness of these units for any specific application.
- Page 3 CONDUCTOR PRETREATMENT All kinds of copper conductors can be clamped without treatment. DO NOT solder tin stranded conductors. The solder yields and fractures under high pressure. The result is increased contact resistance and excessive temperature rise. Additionally, corrosion has been observed due to the fluxes. Notch fractures at the transition from the rigid tinned part to the flexible conductors are also possible. Ferrules can be used as a protection when wiring stranded conductors.
