- 500 VA (CCS) high voltage plate transformer
- 2,500V C.T. R.M.S. secondary: 200ma CCS, 300ma ICAS
- 115 VAC, 50/60 Hz primary (Black & Black input leads)
- Runs full wave bridge or full wave C.T.
- Enclosed 4 hole chassis mount with minimum 6" leads
- Secondary leads exit through rubber bushings (2,000 VAC and above)
- Class A insulation (105 degrees C); Hi-Pot tested at minimum twice secondary voltage
- CSA certified (209651); RoHS and REACH compliant
The 732 is a 700 Series high voltage (plate) transformer rated 500 VA, with a single 115 VAC, 50/60 Hz primary and a 2,500V C.T. R.M.S. high voltage secondary. It suits builders and service technicians who need a centre-tapped plate winding for a rectified high voltage supply running from a 115 VAC line.
The high voltage secondary is rated 200ma under CCS (Continuous Commercial Service) and 300ma under ICAS (Intermittent Commercial or Amateur Service); the 500 VA figure is a CCS rating. The unit can be run in either a full wave bridge or a full wave C.T. rectifier circuit, and the series design guide gives the voltage and current factors for each rectifier and filter arrangement.
Construction is enclosed with a 4 hole chassis mount and minimum 6" long leads. Insulation is Class A (105 degrees C), each design is Hi-Pot tested at a minimum of twice the secondary voltage, and the series is CSA certified (209651). Because the 2,500V C.T. secondary is at 2,000 VAC or above, its leads are brought out through rubber bushings. The part is listed as RoHS and REACH compliant.
Primary wiring for the 732 is simple: the 115 VAC input is on the Black and Black leads. The same 500 VA, 2,500V C.T. rating is also offered as the 732A, which has a dual 117/234 VAC primary. Shipping weight is 17.7 lbs (8.03 kg).
Ideal For
- High voltage plate supplies for vacuum tube equipment
- Full wave bridge rectified high voltage DC supplies
- Full wave centre-tapped (C.T.) rectifier supplies
- Amateur radio (ICAS) intermittent service

Frequently Asked Questions
What are the ratings of the 732?▾
The 732 is rated 500 VA (a CCS rating) with a 115 VAC, 50/60 Hz primary and a 2,500V C.T. R.M.S. secondary rated 200ma. CCS and 300ma. ICAS.
What do CCS and ICAS mean?▾
CCS is Continuous Commercial Service and ICAS is Intermittent Commercial or Amateur Service. The VA rating is specified as CCS.
How is the 732 primary connected?▾
It is a 115 VAC only model; the input is on the Black and Black leads.
What rectifier circuits can it be used with?▾
The unit can be run full wave bridge or full wave C.T.
What is the difference between the 732 and 732A?▾
Both are rated 500 VA with a 2,500V C.T. secondary. The 732 has a 115 VAC primary; the 732A has a dual 117/234 VAC primary.
How are the high voltage leads brought out?▾
At 2,000 VAC and above the secondary leads are through rubber bushings, which applies to the 2,500V C.T. secondary of the 732.
