It's a full-service, reduced-voltage controller for electric fire pumps with motors designed for wye-delta starting. Every FD70 is built to order, so we quote each one to your motor, voltage, enclosure and options.

This reduces the motor's starting current significantly, and wye-delta is the only starting method with a starting torque efficiency of 100%. In open transition, the motor is briefly disconnected while the windings switch from wye to delta. The \u003ca href=\"\/products\/eaton-fd80-wye-delta-closed-fire-pump-controller\"\u003eFD80 closed transition\u003c\/a\u003e keeps the motor connected through the changeover. Wye-delta starting requires a motor with its windings brought out for wye-delta connection. The FD70 can be programmed for fully automatic or semi-automatic operation.\u003c\/p\u003e\n\u003cp\u003eOther starting options include the \u003ca href=\"\/products\/eaton-fd30-across-the-line-fire-pump-controller\"\u003eFD30 across-the-line\u003c\/a\u003e, \u003ca href=\"\/products\/eaton-fd40-part-winding-fire-pump-controller\"\u003eFD40 part winding\u003c\/a\u003e, \u003ca href=\"\/products\/eaton-fd60-autotransformer-fire-pump-controller\"\u003eFD60 autotransformer\u003c\/a\u003e and \u003ca href=\"\/products\/eaton-fd90-soft-start-fire-pump-controller\"\u003eFD90 soft start\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch2\u003eEPCT Fire features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e7\" color touchscreen:\u003c\/strong\u003e 800x480 high-resolution display, a fast processor that reduces input lag, and a simplified tab system for navigation and programming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSB port:\u003c\/strong\u003e download history, statistics, configuration, diagnostics and start-up files; upload a configuration to reduce programming time; update firmware\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEvent history:\u003c\/strong\u003e logs up to 65,000 time-stamped events, with on-screen filtering for troubleshooting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProgrammable output relays\u003c\/strong\u003e for common alarm, power\/phase failure, phase reversal and pump run\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptional boards:\u003c\/strong\u003e\n  \u003cul\u003e\n  \u003cli\u003eRelay board: four (4) one form-C programmable output relays\u003c\/li\u003e\n  \u003cli\u003eMODBUS board: output communication via RS422 or RS485\u003c\/li\u003e\n  \u003cli\u003eSecondary 4-20mA device board: additional connections for external pressure transducers, temperature sensors and similar devices\u003c\/li\u003e\n  \u003cli\u003eAlarm board: a supervisory powered alarm output\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosures:\u003c\/strong\u003e UL Type 2 (drip-proof) standard; Type 3, 3R, 4, 4X and 12 available\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards:\u003c\/strong\u003e built to NFPA 20 and listed to UL 218.
