Introducing

Three Phase Automatic Changeover with Current Limiter (TPN ACCL)The Intelligent start-up solution

ACCL

Three Phase Automatic Changeover with Current Limiter (TPN ACCL) The Power instability in developing countries along with the inefficient rationalized power distribution creates a need for the alternative source of power, to back up the utility supply. This further necessitates the automation, in the distribution system as the rate of power outage & low voltage output becomes predominantly high. Most of the Residential & commercial processes are dependent on power supply & if the process of changeover is manual, this will not only create the hindrance in important activities but it may also damage the device or machine from human error during the changeover.

Havells TPN ACCL is a fully automatic high precision microcontroller based device and is ideally suited for proper/efficient utilization of standby generator used in multi-storied apartments, commercial complexes, etc.

Functions1. When the Mains Supply is available: Automatic mode:• TheTPNACCLallowsfullloadcurrentoneachphasewhenall

the 3 phases of mains supply is available, and when any one of the phase fails, TPN ACCL will automatically senses and actuates the inbuilt changeover mechanism to the generator supply.

Manual mode:• IfRphaseisavailable,itwillcountinuetoruntheloadonmain

supply irrespective of the availability of other phases. But if R phase fails, the TPN ACCL will automatically senses and actuates the inbuilt changeover mechanism to the generator supply.

Note:ItisrecomendedtoconnectallessentialloadtoRphase.

2. When the Mains supply fails With AGS (automatic generator start feature):• TPN ACCL provides signaling through a potential free contact

for starting the Generator.

Without AGS (automatic generator start feature):• When the mains supply goes OFF, a consumer is automatically

connected to the generator in case generator supply is available, after a time delay of 8-12 seconds in order to limit the sudden load on the generator.

• TheTPNACCLhasacurrent limitingfeatureonthegeneratorside.Iftheloadexceedstheallowablelimit,TPNACCLwillgiveapre-trip indication and after a delay of 5 second, TPN ACCL will trip and goes on hold. After a predetermined time delay (say 8 sec), it will again check the connected load and gives the supply if the load is under the allowable limit. During this period, the consumer is expected to switch off the non-essential loads and reduce it within the limit. The overloaded phase will be indicated through LED.

• Inanunlikelyevent,iftheconsumerdoesnotswitchoffthenon-essential loads to reduce it to within the limit, supply to the load is automatically disconnected after 5 cycles of interruption.

• Thesupply frommains to the loadcanbe restoredonly afterpressing the Reset button present in the front of TPN ACCL.

3. When Mains supply is restored

• As soon as the main supply restores, the load is automatically transferred to the mains supply after a delay of 2-4 sec.

• WithAGS,TPNACCLitselfgeneratesthesignaltoautomaticallystop the generator
