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

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
