28 QPAC User's Guide Appendix
To order, complete the code number
to the right with the information below:
QPAC = Modular power controller; phase angle, burst,
or solid-state contactor with fuse(s) and holder(s) included.
Phase
01 = Single phase
32 = 3-phase, 2-leg
33 = 3-phase, 3-leg
Operating and Output Voltage
12 = 120V~ (ac)
20 = 208V~ (ac)
24 = 240V~ (ac)
27 = 277V~ (ac)
38 = 380V~ (ac)
41 = 415V~ (ac)
48 = 480V~ (ac)
57 = 575V~ (ac)
Cooling Fan Voltage
3
Customer to supply wiring and hook-up.
1 = 120V~ (ac); required on all 3-phase models
2 = 240V~ (ac); required on all 3-phase models
Output Current (Amps)
150 = 150 amps
200 = 200 amps
300 = 300 amps
400 = 400 amps
500 = 500 amps
600 = 600 amps
800 = 800 amps
01K = 1000 amps
Input Control Card
CA = Solid-state Å (ac) input (08-5285) contactor
CD = Solid-state Î (dc) input (08-5286) contactor
BF = Burst fired, fixed time base (08-5289) 4 to 20mA
BV = Burst fired, variable time base (08-5342) 4 to 20mA
AF = Phase angle fired (08-5288) 4 to 20mA, not available on Q32.
AL = Phase angle fired w/current limit (08-5411) 4 to 20mA, not available on Q32. Includes one
current transformer. Add a second CT for 3-phase, 3-leg models.
AL models 150 amps and above require one interstage transformer.
Open Heater/Shorted SCR Detector
4,5
(burst fire, zero cross models only)
0 = None
1 = Single-phase operation
2 = Three-phase operation
