PG-MSR Series leads single phase Motor Starting Relay.
upgraded functions and lower price.

Features

* What is features of our PG-MSR?

1. PG-MSR is non-contact single phase motor starting relay adapting the semi-conductor element.
(an existing starting relay adapt an centrifugal force switch method).

2. approved by Korean Patent; voltage compensation circuit .

3. Terminal and Wire connecting way

1) Withstanding voltage was increased 2 times for 220V Motor.
Adapting a series connection of 2 Triac and an unbalance control circuit, PG-MSR can withstand 2 times of voltage.
so, PG-MSR can cover withstanding voltage max 1,200V and rated current 50A.
So, the frequent burn-out trouble caused by high voltage of 220V Motor doesn't happen.
Even single phase motor can run 2~3Hp by our PG-MSR.

2) Off voltage is automatically controlled by the power voltage.
By adapting our patent voltage compensation circuit, motor run well at the high voltage and even under voltage,(ref. graph)
PG-MSR run well under the frequent cut-off circumstances using a long and thin power line like Agricultural motor.

3) Safety is increased by combining a Zero-Crossing control switching circuit and a reactor.
4) Capacity of reactor is reinforced.
By our patented Reactor manufacturing method, the reactor capacity is reinforced several times.
Whereas, existing reactor can be frequently burn-out by a small capacity to install the reactor inside a little space.

5) By the undervoltage trip circuit, motor can be protected at the undervoltage, even if other starting relay can not run motor.
When motor can not run below 50% of rated voltage, our PG-MSR cut off. And motor can be protected by cutting off the current of starting condenser.

6) PG-MSR is off at 65~70% of starting coil voltage and run again at 30% of starting coil voltage.
7) The contact, arcless and long lasting life doesn't easily wear out and safe against burnout.
Better at the moisture, dust, collision and trembling.
most efficient at frequent starting, stop and reversion

8) Easy installment by diverse connecting way and size
can be installed at the inside/outside of motor and at long distance.
