Control transformers are designed for voltage conversion applications with high inrush that require reliable output voltage stability, such as where electromagnetic switching devices are used. Hammond ACP series 1-phase open core control transformers offer 480x600 VAC primary to 120x240 VAC secondary configurations in a range of VA ratings.
Hammond HPS Spartan industrial open core and coil control transformers offer an efficient and economical solution for applications where high inrush or machine tool duty are not necessary. The units are well suited for HVAC applications, signal and alarm systems, motor control circuits, lighting and circuit isolation.
The HPS Spartan control transformers are open style units in ratings from 50VA up to 5000VA. Units from 50VA to 3000VA (30 amps) include molded terminal blocks. Optional finger guards and a fuse block adapter kit are available.
Four series of open core control transformers are available:
