Technical Specifications of Thyristors:
3KW Single phase to 100KW Three phase
Single phase, Two phase, Three phase (3 or 4 wire star and 3 or 6 wire delta)
Phase angle control (self synchronized)
(4-20)mA / (0-10)VDC / Potentiometer
0 to 230VAC or 0 to 415VAC variable voltage proportional to the control signal.
Adjustable Ramp Up and Ramp Down Time for soft increase and decrease of output voltage.
Using on card Current Limit and Trip settings. Settings For adjusting voltage and current per phase using on card presets.
Suitable for both resistive and inductive / transformer load (15A to 500A @230/415 VAC)
240/380/415 VAC, 50/60 Hz. (User should specify)
a) Semiconductor fuse per phase – to protect thyristors against short circuit condition. RC snubber / MOV across the SCRs to protect against transients.
b) Thermal cut out switch on the heat sink – to protect thyristors against over heating
c) Cooling fan on heat sinks for thyristors above 50Ampere
d) Heavy duty input/output terminals or Copper Bus bars for supply and heater Connections.
Power pack can be mounted on the base plate of the control panel Partners In Measurement And Control
