5. GENERAL TECHNICAL DATA & SPECIFICATIONS

LOAD, FIRING, DIAGNOSTICS & RATINGS

AC 51 resistive or low inductance loads

CATEGORY OF USE

AC 55b infrared lamps

(Tab. 2 EN60947-4-3)

AC 56a: transformer loads

PA - Load management by adjusting the firing angle (only configuration

single-phase or delta open)

ZC - Zero Crossing with constant cycle time (settable in range 1-200sec)

BF - Burst Firing, or D.O.T. with variable cycle time optimized min.

Trigger Mode

HSC - Half Single Cycle corresponds to Burst Firing that includes ON and

OFF half-cycles.

Useful for reducing flicker with short-wave IR loads (applied only to single-

phase resistive or 3-phase 6-wire open delta loads).

V, V

: Voltage feedback proportional to RMS voltage value on load

(useful to compensate possible variations in line voltage).

I, I

: Current feedback: bound to RMS current value on load to compensate

Feedback Mode

variations in line voltage and/or variations in load impedance.

P: Power feedback: proportional to real power value on load (useful to keep

constant values of electrical power assigned regardless of load impedance

or line voltage variations).

FUNCTION

Detection of shorted load circuit, absence of line voltage, HB alarm (partial break

Diagnostics

of load)

OPTIONS

- Timed Soft-Start firing ramp, with or without peak current control

- Soft-Start firing ramp (specific for infrared lamps)

Options

- Timed shut-off ramp

- Limitation of RMS current in load

- 0-90° Delay-Triggering for firing inductive loads in ZC & BF/DOT modes.

- SCR in short circuit (presence of current with OFF control)

- Absence of SCR current when under load.

- Overtemperature alarm

Current read

Diagnostic

• HB alarm: interrupted or partially interrupted load

• Automatic calibration of HB alarm setpoint starting from current value in load

• Alarm for load in short circuit or overcurrent

Voltage read

• No line voltage
