Ptc motor starter

The Sensata Technologies 8EA motor starter , a low-cost alternative to electro-mechanical relays, performs the PTC (positive temperature coefficient) solid-state starter func- tion. The 8EA is suitable for compressors used in refrigerators, freezers, water coolers, de-humidifiers, vending machines and similar . Provides inherent start–winding protection. Optimal packaging approach improves efficiency.

Used in 120V or 240V applications.

It performs the PTC (positive temperature coefficient) solid–state starter function.

PTCR Motor start packages can be economical solid state torque assist for heat pumps, room air, commercial and residential air conditioning and refrigeration systems.

Compared to the alternative start capacitor . In general, if the PTC starter produces sufficient starting torque, it is considered the simplest and most economical choice. SIMPLIFIED PTC STARTING DIAGRAM. PTC , which is at low resistance , provides . Brief Introduction: PTC Thermistors for motor-starting are mainly used in the circuit of refrigerator and air-conditioner motor-starting, frequency conversion air- conditioner-starting, motor over-heating protection.

This article presents how to test them to . When the motor starts, the resistance of the thermistor will initially be very low and sufficient . Klixon 8EA series positive temperature coefficient ( PTC ) Motor starter. Simple starter circuit for single-phase AC motors.

Current control, over current protection. Detector element using change of heat dissipation factor. Constant voltage and constant current equipment.

If the motor design allows it, it will increase start torque due to the additional phase shift of the current passing through the start winding.

Low cost PTC devices increases torque 3to 5percent! American made ICM motor starters with patente solid state circuitry stand for quality. Includes Internal Back-up Protection.

System for the PTC motor starter.

It should be pointed out that these . PTC thermistors are given in Figure 2c.
