CENTRAL POWER SYSTEMS

These systems usually comprise a large battery of between 10 Ah and several hundred Ah charged by a sophisticated system to maximize battery life and in the case of vented cells to minimize electrolyte loss. Larger scaled lead acid batteries are available with a design life in excess of 10 years.
These function in the same way as vented cells but require no maintenance.

Powerlight XPS System
  • Chargers are electronically controlled.
  • Designed to operate at full power in ambient temperatures up to 40°c.
  • Available for maintained, non-maintained & floating output.
  • Vented cells for easy maintenance.
The JSB range of powerlight plus sine wave static inverters comprises robust reliable central battery systems in which the DC battery is converted to AC at appropriate voltage and frequency.

The main advantage, compared to a central battery system, is that standard mains luminaires may be used, this giving specifiers complete flexibility of design.

MDX Conversion Modules
  • Pulse width modulation techniques.
  • Battery protected against over charging.
  • Constant voltage and current limited charger.
  • Battery protected from deep discharge.
  • Suitable for use with value regulated batteries.
  • Temperature compensated control is included on all chargers.
  • Stabilize the output with an efficient filter to achieve a pure sine wave.
The EASICHECK offers test results and assurance of correct operation for any emergency lighting system.

Answer to this complex problem is the JSB Easicheck addressable emergency lighting test system, which provides the responsible person with test results and assurance of correct operation.
Testing is performed and can be conveniently timed to coincide with periods when a building is unoccupied. Any fault can be easily pinpointed and diagnoses of faults reported automatically at the central control panel. Test results can be printed off quickly, instead of compiling a lengthy hand written records.
