G9EN-1 DC Power Relays
Characteristics
Note: The above values are initial values at an ambient temperature of 23°C unless otherwise specified.
*1. The insulation resistance was measured with a 500-VDC megohmmeter.
*2. The impulse withstand voltage was measured with a JEC-212 (1981) standard impulse voltage waveform (1.2 × 50 µs).
*3. The Upper limit of double amplitude: 10 mm P-P
*4. The mechanical endurance was measured at a switching frequency of 3,600 operations/hr.
*5. The electrical endurance was measured at a switching frequency of 60 operations/hr.
*6. The switching performance and interruption performance were measured with a Zener diode and normal diode connected to absorb coil surge. These performances
will be lower if only a normal diode is used.
