Description

Comar Motor Start Capacitors.

The EL electrolytic capacitor have high capacitance (μF value) able to provide an high starting torque to the motor. It is a non polarized capacitor especially designed for intermittent AC voltage applications for single-phase motors.

TECHNICAL DATA

Working temperature
-45 °C / +65 °C (operating)
-40 °C / +70 °C (storage)
Endurance test 500 h
Dissipation loss angle
Measurement frequency: 50 Hz, the typical value shall not exceed 0,10, calculated as follows: Tan d = W / (V x I) = (true watts / apparent watts)
Capacitance measurement
Capacitance shall be determined by measuring the current – after 2/3 sec. of energising – through the capacitor at rated voltage and frequency. The capacitance is defined as follows: C = (I x 10^6) / (2 π^2 x f x V)
