Introduction
The Model FBCS-2K Series Power Supply has been designed to charge forklifts and it is based on two (2)
PWS 1000d power supply connected in parallel and placed in a metal enclosure. It supplies 27.2 VDC from
a 110 Vac electrical system. A state of the Art Switchmode design offers high reliability, high efficiency and
minimum size.
All new Current Mode switching design offers increased power and reliability in a compact package. Extra
input and output filtering reduce EMI to extremely low levels. Reliability features include an input fuse,
thermal shutdown, current limiting and output short circuit shutdown with automatic recovery. The output
voltage is easily adjusted 1.0 volts above or below the standard output voltage. The model PWS1000 Power
Supply supplies either 12, 24 or 48 VDC from a 110 or 220 VAC power source. High quality digital meters
can be added (factory option) to allow monitoring of charging current and charging voltage. Other output
voltages up to 72 volts are also available by special order.
Below electrical specifications are per one unit model PWS1000d.
