Microprocessor-controlled exciter system PDL-2

for synchronous motor

It is to regulate and control the excitation system of the brush synchronous motor of all kinds of factories, mines and enterprises of each load and capacity, such as the synchronous motor of large and medium pumps, ball mill, air compressor, etc. It can work under different operation conditions of power plants, mines and factories and realize “Unattended Operation (few on-duty)”. Features -Standard embedded structure -3-phase fully-controlled bridge -Self-adaptive regulating method -For the large power, it can be designed with the dual bridges or the multi-bridges -Multi-bridge current-equalizing coefficient > 0.95 -Foolproof operation -Direct display (touch screen being optional) -Great impulse driving capability -Complete self-check function -Self-restoring function -Complete testing function -Complete limiting protection function -Excellent control rules -Reliable dual-power supply -DI & DO -RS485 and Ethernet communication It forms the dual Ethernet networks when using 2 sets of excitation regulator for the control and regulation, and the Ethernet when there equips with only one set of excitation regulator; -Technical parameters -AI parameters: -Terminal voltage: PT 100V -Stator current: CT 5A or 1A -DI: 8 loops of dual optical isolation signals input -A/D conversion resolution ratio: 4096 12 loops -Auto/manual regulating range: (5～130)% of ratings -Voltage regulation accuracy: ≤±0.5%
