1. Reference for selecting the current capacity of the power regulator
General pure load: The current capacity of the power regulator should be greater than the maximum current of the load
Silicon carbon rod load: When the transformer is cancelled, the silicon carbon rod should be connected in series so that it can withstand more than 70%~80% of the power supply voltage. Silicon carbon rods have a negative resistance zone at 700-800ºC, and the current capacity of the power regulator should be greater than 1.7 times the maximum current of the load.
Electric heating tube load: The electric heating tube is susceptible to moisture, local short circuit and discharge sparking, etc. The current capacity of the power regulator should be greater than 1.7 times the maximum current of the load.
Transformer load: It should have a current limiting function, and the current capacity should be greater than 2-2.5 times the maximum current of the load.
The current capacity should be increased for special loads, please state it when ordering.
2. Ordering example: PA300B-I-3-100-A-O-M
Indicates: PA300B series three-phase intelligent power regulator; input signal is 4-20mA; load is triangle or star center not grounded; load rated current is 100A; has overcurrent protection current limiting function; manual function is valid; can be manually switched control.
PA300B Series
Two working modes: voltage regulation and frequency division zero-crossing power regulation
With slow start, slow shutdown, and adjustable slow start time
Additional current limitation, overcurrent protection and other functions
