Hoffman Controls 792-ECM ECM Speed Controller

ECM Speed Controller

The ECM Speed Controller is a simple and efficient way to maintain your boiler's temperature. It automatically maintains steam pressure by modifying the output of the steam turbine governor.

Hoffman Controls 792-ECM ECM Speed Controller. Implementing the latest technology in electronic standard motor control, the ECM is designed for the most economical and precise control of a single- or 3-phase AC induction motor. Its enhanced features include multiple diagnostic capabilities, allowing easy troubleshooting on-site.

The Hoffman ECM speed controller operates electric motors on constant (ECM) and variable (EMV) voltage levels. It produce speeds from 0 r/min to a maximum of 1545 r/min with manual reverse.

A rugged, cast-aluminum housing is designed for maximum motor protection and long service life. The versatile ECM 792-ECM speed controller comes with four selectable field programs called modes: temperature control (TC), differential (DIFF), proportional plus integral (PI-plus), and proportional integral (PI). All modes apply a proportional offset to the setpoint. A graphic display shows the operating mode, output setpoint, actual output value, and time since last reset. Requires mounting hardware and an internal capacitor. Standard features include protection against thermal overload or low voltage; automatic restart after an output failure; high current

Hoffman Controls 792-ECM speed controllers are designed for pool and spa pumps. It uses the latest solid state technology in a 12 volt, permanent magnet motor drive. The 792-ECM is a closed loop responsive controller with electronic commutation using lock-up torque reversion. The ECM series is designed for sensitive and light duty applications requiring accurate speed control. This controller will operate multiple pumps in parallel or series with this feature providing maximum pumping ability with minimum energy consumption.

Add precise speed control to new or existing systems with the 792ECM speed controller. It is specifically designed for use in light industry, material handling, and commercial applications. Features include microprocessor-based control technology and onboard diagnostics for increased reliability, control of DC motors from 0.8 to 5 hp at 10% to 100% rated torque performance, 2-wire serial interface compatible with most fieldbuses, Power: 0.2 HP Single phase 230/460VAC 50/60 Hz +5%/-3% (0.8) 1 HP Single phase 230/460VAC 50/60 Hz

"ECM" stands for Electronic Current Monitor. This feature is designed to monitor the voltage being supplied to the heater core so as not to exceed 15 amps. This will provide an added peace of mind for the customer.
