Specification Brand : PULME BulletPoint : SSR-40LA 4-20mA Input AC 24-380V 40A Output 1 Phase Voltage Regulator Solid State Relay SSR BulletPoint1 : The input adjustment range is wide, the output adjustment precision is high, the three-phase symmetry is good, and the anti-interference ability is strong. BulletPoint2 : There is a phase loss protection function. When the module is out of phase due to three-phase electrical input or the voltage is unstable, the module will immediately turn off the three-phase output to avoid load damage, so as to avoid production loss. BulletPoint3 : The input control has a wider adjustment range, a finer signal resolution, and a higher output voltage regulation accuracy. BulletPoint4 : The product is also suitable for the speed regulation of small power three-phase torque motor, and the speed regulation of fans, pumps, etc., and can also be applied to the slow start of AC motors.
