Manual Control
The FC36M firing circuit has a 5Vdc output that can be used to supply the clockwise end of a 5K ohm potentiometer. The wiper is connected to the terminal marked SIG
I/P and the counterclockwise end to 0V.
Voltage control
For control using a remote dc signal the positive input should be connected to the terminal marked SIG I/P and the negative input to be connected to 0V. The input
impedance is 10K ohms for 0-5V input and 20K ohms for 0-10V input.
Current control
For current control connect a 4-20mA dc signal between terminals marked 4-20mA and 0V. This input can also be used as 1-5V dc input. The input impedance is 240
ohms.
Phase Angle control
Option 1 - the switch marked SW1 should be switched to the on position. This position connects terminals A with 5V.
Option 2 – (see Soft Starting) the switch marked SW1 can be switched to the OFF position. The OFF position isolates the inputs and disconnects terminals A from 5V.
Inputs (A and C) then require an external supply between 5 and 24V dc.
Burst Firing control
The switch marked SW1 should be switched to the OFF position and the terminal marked B should be linked to5V.
Phase Angle to Burst Firing control
The switch marked SW1 should be switched to the ON position and terminals A and B should be linked together. The firing circuit will start in phase angle mode and
switch to burst mode when the control signal ramps up to the set point. It will stay in the burst mode even if the signal drops below the set point. It will restart in phase
angle mode when the unit is switched off or reset.
Soft Start
When the FC36M is initially powered up the output is inhibited for 0.5 seconds, then the soft start is automatically enabled and the firing circuit will ramp up at a rate
determined by VR3 (0-30 seconds). The ramp time relates to full conduction, for example, if the ramp time is set to maximum (30 seconds) and the set point is 50% the
controller will ramp to the set point in 15 seconds.
INTRODUCTION
The complete enclosed three phase Dual Mode Power Regulator (DMPR3)
thyristor assembly provides control of inductive/resistive loads of up to 54kW
at 415V. The user selectable control modes, via the internal switches are
either phase angle, burst firing or a combination of the two i.e. start up in
phase angle and then continue in burst firing. The controllers also come with
frequency tracking allowing the unit to be installed in many applications
where the supply is unstable. There are a number of signal control options to
meet most industrial requirements.
All are housed in a bespoke enclosure and have easy access to internal
signal & power terminals for simple installation. With Integral semiconductor
fuses and heatsink the controller offers a solution for many application
requiring single or dual mode control.
APPLICATIONS
Suitable for furnaces, ovens, dryers, air curtains, hot plates and many other
heating and ventilation applications.
