KR440 AVR Generator Regulator Automatic Voltage Stabilizer Single 3 Phase AC Brushless Alternator output Voltalge Control Module

1. Description

KR440 Voltage Regulator (AVR) is a sealed electronic device that adjusts the rectified output power of the exciter armature by controlling the low-power exciter magnetic field, so as to achieve the control host.

Magnetic field current, stable output voltage requirements of brushless generator, with low frequency and no input signal protection device. It is also equipped with parallel compensation function, which meets the needs of customers to expand capacity.

2. Specifications

Input power: 170V ~ 265VAC, 50/ 60Hz

Detection power: 190V~270VAC 340~520VAC 50/60

Maximum output: 4A 95VDC

Voltage regulation rate: ≤0.5%.

Generator Field Resistance: 15 ohms minimum.

External potentiometer: 1KQ 1/2W potentiometer ±8%.

Voltage build-up (initial stage):

When the residual magnetism voltage is greater than 5V25Hz, the voltage will be established automatically. The low-frequency protection has a built-in protection circuit that reduces the output voltage when the engine speed decreases (refer to Figure 3)

Operating temperature: -40 C~60 C.

Size: 163mmL*138mmW*45mmH
