The 712A is a 293 VA high voltage (plate) transformer from the 700 Series with a 117/234 VAC, 50/60 Hz primary and a 850V C.T. secondary, intended for builders and service technicians who need a centre-tapped plate supply. It is the dual-primary version of the 712, providing an 850V C.T. secondary from a 117 VAC or 234 VAC supply.
The high voltage secondary is rated 345 mA under CCS (Continuous Commercial Service) and 518 mA under ICAS (Intermittent Commercial or Amateur Service); the 293 VA figure is a CCS rating. The transformer can be run full wave bridge or full wave C.T. For 117 VAC input, connect Blue to Black and Brown to White; for 234 VAC input, connect Brown to Black and apply input to Blue and White. A 115 VAC-only version is also listed as the 712.
Construction is enclosed, with a 4 hole chassis mount, minimum 6 in long leads and Class A insulation (105 degrees C). Units are hi-pot tested at a minimum of twice the secondary voltage and the series is CSA certified (209651). The 712A is RoHS and REACH compliant, with a series-table weight of 8.8 lbs (3.99 kg).
Ideal For
- 850V C.T. high voltage plate supply
- Full wave bridge or full wave C.T. rectified supplies

Frequently Asked Questions
What is the difference between the 712A and the 712?▾
The 712A has a dual 117/234 VAC primary; the 712 is the 115 VAC primary version with the same 850V C.T. secondary and 293 VA rating.
How do I wire the 712A primary?▾
For 117 VAC, connect Blue to Black and Brown to White. For 234 VAC, connect Brown to Black; input is Blue and White.
What do the CCS and ICAS current ratings mean?▾
CCS is Continuous Commercial Service (345 mA for this part) and ICAS is Intermittent Commercial or Amateur Service (518 mA). The 293 VA rating is a CCS rating.
Can it be used in a full wave bridge circuit?▾
Yes. Units in the 700 Series can be run full wave bridge or full wave C.T.
How is the 712A mounted and insulated?▾
It is an enclosed unit with a 4 hole chassis mount, minimum 6 in long leads and Class A insulation rated 105 degrees C.
