PSA-03-50 : SINGLE PHASE SCR POWER REGULATOR

รหัสสินค้า : PSA-03-50

DESCRIPTION

• Resistive load control device such as Heater. Working model is Phase

Angle Control, which controls the phase angle of the Sine Wave signal.

The power of the load changes with the input signal. Control resolution

equipment

• Receive signal Input 4-20 mA, 1-5 VDC, 1 KOhm (Potentiometer),

and Contact

• 4 Function Modes: Phase Angle Control, ON/OFF, Cycle Control and

RS-485 MODBUS RTU

• Used with 50 A current load at 220 VAC 50 Hz

• LED display status and error display

• SCR protection in case of over 85 ํC with Semi-Conductor fuse

• PSA-03-50 has Heat Sink for Cooling

OPERATION

PSA-03-50 can accept many types of inputs. By setting the operating mode. If set to Phase Control will control the angle of the

phase as a percentage analog signal input lf set to Cycle Mode will affect the setting. Period, ie set period 0.5 sec. Input 50% input will be

ON (50%) = 0.25 Sec. And OFF (50%) = 0.25 Sec. If ON/ OFF mode is ON/ OFF (100%) according to the Contact Input, if Mod bus RTU

Mode is connected to the computer and operation control via RS-485 communication.
