- 345 VA (CCS) high voltage plate transformer
- 1,500V C.T. R.M.S. secondary: 226ma CCS, 339ma 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
- Class A insulation (105 degrees C); Hi-Pot tested at minimum twice secondary voltage
- CSA certified (209651); RoHS and REACH compliant
The 724 is a 700 Series high voltage (plate) transformer rated 345 VA, with a single 115 VAC, 50/60 Hz primary and a 1,500V 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 226ma under CCS (Continuous Commercial Service) and 339ma under ICAS (Intermittent Commercial or Amateur Service); the 345 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 724 is simple: the 115 VAC input is on the Black and Black leads. The same 345 VA, 1,500V C.T. rating is also offered as the 724A, which has a dual 117/234 VAC primary. Shipping weight is 12 lbs (5.44 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
