Auto Source Change Over with Current Limiter
Auto Source Change Over with Current Limiter
Prok devices make ACCL has applications in high-rise buildings and commercial complexes. Whenever power is rationed generator supplying the load in absence of regular EB supply. Three phase and single-phase units with suitable current ratings can be used for this purpose.
Benefits
- Microprocessor based, hence precise and accurate.
- Over voltage & Under voltage cut off for EB & DG
- Simplifies electrical complexity
- Significant saving on wall space & wiring.
- Product guaranteed for 2 years
- In the event of change over from DG to EB the phase is first isolated, then the neutral is disconnected (Single Phase ACCL)
- Three phase ACCL are enclosed in aesthetically made powder coated sheet metal enclosures.
- Single phase ACCL are enclosed ABS grade thermoplastic.
- Mechanical inter lock between contactors in three phase models.

- While monitoring the mains supply, it allows full load current.
- While monitoring the generator supply, allows only limited load and functions as load limiter as per desired power and current.
- Current sealing (while monitoring the Generator) will be preset at factory.
- Whenever the load current exceeds the preset limit, power is automatically switched off instantaneously and reset automatically after 9 seconds and trips again if the over load still exists, this cycle is (3Sec ON & 6Sec OFF) is repeated every 9 seconds. ACCL enters lock out mode after five ON & OFF cycles if over loading of the DG persists.
- Display of each phase Voltages, Currents and power (In three phase ACCL)
- Over voltage and Under Voltage cut off for both EB/DG (In three phase ACCL)
