- 510 VA (CCS) high voltage plate transformer
- 1,020V C.T. R.M.S. secondary: 500ma CCS, 750ma ICAS
- Dual 117/234 VAC, 50/60 Hz primary
- Runs full wave bridge or full wave C.T.
- Enclosed 4 hole chassis mount with minimum 6" leads
- Class A insulation (105 degrees C); Hi-Pot tested at minimum twice secondary voltage
- CSA certified (209651); RoHS and REACH compliant
The 717A is a 700 Series high voltage (plate) transformer rated 510 VA, with a dual 117/234 VAC, 50/60 Hz primary and a 1,020V 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 and want the flexibility of either a 117 VAC or 234 VAC mains connection.
The high voltage secondary is rated 500ma under CCS (Continuous Commercial Service) and 750ma under ICAS (Intermittent Commercial or Amateur Service); the 510 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). The part is listed as RoHS and REACH compliant.
Primary wiring for the 717A: for 117 VAC input, connect Blue to Black and Brown to White; for 234 VAC input, connect Brown to Black and the input is Blue and White. The same 510 VA, 1,020V C.T. rating is also offered as the 717, which has a 115 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 717A?▾
The 717A is rated 510 VA (a CCS rating) with a 117/234 VAC, 50/60 Hz primary and a 1,020V C.T. R.M.S. secondary rated 500ma. CCS and 750ma. 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 do I wire the 717A primary for 117 VAC or 234 VAC?▾
For 117 VAC input, connect Blue to Black and Brown to White. For 234 VAC input, connect Brown to Black; the input is then Blue and White.
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 717 and 717A?▾
Both are rated 510 VA with a 1,020V C.T. secondary. The 717 has a 115 VAC primary; the 717A has a dual 117/234 VAC primary.
What certifications does it carry?▾
