AMF Control Relay

Function:
Power House AMF relay: is a solid state, compact electronics device developed to make AMF panel reliable, simple, and easy to operate. It has built in Mains voltage Sensor, incoming delay timer, starting attempt timer with ON delay and OFF delay, 3 Attempt and lock, DG voltage sensors, counters, logic control etc. Incoming High Voltage supplies are isolated by opto-couplers and out put  connections are through electrotechnical relays.  The relay does not require any separate power supply. It works on DG set starting battery.

Application:
Automation of DG sets.                                                

Auto Load Changeover  Relay
with Load limiter - a perfect solution for power sharing

Automatic Load Changeover Relay (PLCR) - is a high precession system for efficient distribution of generator power in multi-storied apartments, commercial complexes etc.  
Series PLCR-DS are designed to connect mains supply  to load till mains is present.  On mains failure and receiving generator power, it connects the load to DG supply. During DG operation, load drawn is monitored. If the load exceeds the allotted limit, it disrupts the supply and rechecks in intervals. On reducing the load and keeping it within the limit,  load is connected to DG supply.  
For different applications, we have specific models. They are with load limiter, without load limiter, transfer of load from one phase to other phase and many additional functions

• Automation at no extra cost.
• Generator power to all lighting points.   
• No separate wiring is   required.
• Assured availability of allotted current
• Space Saving
• Tamper proof & maintenance free.
• Safeguards Generator
• Fully solid state
• LED indication  
• Wide range of single & three phase models.

Water Level Controller
WL21P a low cost, reliable, IC based water level controllers. It keep constant watch on the water level and switch on or off the pump motors subject to availability of water at the reservoir and requirement level set at the upper tank.

Working Principle:
Series PWL21P is designed to operate with electrode type to sense the water level. Stainless Steel sensors with connector box are installed both at over head tank and reservoir.

No dry run of motor and No over flow of water:
Sensors installed in the reservoir senses the availability of water in it. The sensors at the overhead tank is preset with a level at which the pump is to operate and switch off on reaching upper level. The pump is switched on only if the water is available at the reservoir. The system ensures no over flow from the overhead tank and no motor burn out due to dry running .

AUTO/MANUAL/OFF Selection:
The controller has AUTO/ MANUAL/ OFF selection switch on the front panel. Under manual mode pump can be switch on manually, if the switch is in center- Off position, motor remains OFF. This option may be required in emergencies and for cleaning up the electrodes or water tanks.

Protections:
The controllers has built in protections for
A) Over/ Under Voltage Protection
The controller protects the motor from running at low/ high voltage thus saves the motor burnout.
B) Over Load Protection:
Electronics based over load circuit switches off the motor if load drawn exceeds the pre-set value and thus protects the pump motor from Damages.
Indications:
The controller is provided with following LED indications:

A) UNDERVOLTAGE      B) OVERVOLTAGE

C) OVERLOAD             D) PUMPON

E) LOWTANK               F) FULLTANK

G) MAINSON

Housing:
The controllers are housed in sheet steel enclosures finished with Power Coating paints. They are suitable for wall mounting.

Direct operation:
Up to 2 H.P. 1 Ph. Phase
On demand, higher rating can be supplied.
