Article number: K125-10B, K12510B
Specification:
Output power (with a 240Vac input):
10 Adc @ 125 Vdc maximum continuous.
20 Adc @ 250 Vdc boost for 10 seconds.
AC input power:
180 to 280 Vac, single-phase or three-phase, 50 to 400 Hz, 1750 VA maximum continuous load
AC sensing voltage:
90 to 140 Vac, 50/60 Hz; single or three phase.
External voltage adjustment rheostat:
10k ohm, 2W, potentiometer
Control accuracy:
±0.5% answers on average
Voltage operation:
±1% voltage variation for a change of 40°C (104°F).
Response time:
< 4 milliseconds
Frequency compensation:
1 or 2 V/Hz jumper selectable with knee adjustable from 45 Hz to 65 Hz.
EMI attenuation:
