Three Phase Power Controller - 7300A

These units consist of three thyristor controlled channels each rated at the specified current and voltage.

• Current range from 16 to 160A at 45°C

• Voltage up to 500V

• Input current: 0-20mA or 4-20mA

• Input voltage: 0-5V or 0-10V

• Firing modes:

  • Phase angle

  • Fast cycle

  • Single cycle

  • Advanced single cycle

  • Transformer burst firing

• Suitable for virtually all load types

• Current limit option

• Digital communications

Firing Modes

The 7300A is available with a selection of firing modes to suit most applications. It is suitable for controlling resistive loads with high or low temperature coefficient, short wave infrared (SWIR) or inductive loads, including transformer burst firing.

Control modes

7300A units use one of the following:

• RMS load voltage squared (V²),

• RMS load current squared (I²)

• Load power (P)

• Open loop (OL) 

Limits and alarms

Optional current limit, which can work in all firing modes, prevents excessive currents from flowing in the load circuit.
