TECO Westinghouse L510-101-H1-U variable frequency drive. 1 HP (0.75 kW), 115V single-phase input, 230V three-phase output, 4.3A constant torque, 150% overload, IP20 open chassis. The standard fix for running a three-phase lathe, mill, drill press, bandsaw, conveyor, pump, or exhaust fan off ordinary 120V wall power — no rotary phase converter required.

Tested and working. Powers up immediately, LED display and keypad fully functional, MODE and arrow navigation responds, FREQ SET potentiometer adjusts the setpoint through its range, RUN ramps the drive to commanded frequency with the FWD indicator lit, and STOP decelerates cleanly. No fault codes at any point. Continuity and resistance checks on the input and output terminals came back clean — no shorts across T1/T2/T3, no short to ground, no short across the input. Tested without a motor connected, so output performance under load is not verified.

Features: 5-digit LED display, built-in speed potentiometer, RUN and STOP/RESET keypad, V/F control with auto-torque boost or sensorless vector operation, 0.01 to 650 Hz output, RJ-45 communication port, and a full control terminal strip (RA, RB, COM, S1 through S5, 10V, AVI, ACI, AO, AGND) for remote start/stop, multi-speed, and analog speed reference.

Condition: used, pulled from service. Light scuffing and fine scratches across the front face, most noticeable below the STOP/RESET button, plus general shop dust. Keypad, potentiometer knob, LED window, RJ-45 port, and all terminal screws present and intact. No cracks, no missing pieces, no burn marks or heat discoloration. Ships with the 120V line cord shown, landed on L1(L) and L3(N) with the ground under the chassis screw — plug and play for bench testing, or pull it and land your own.

Dimensions: 5.67 in H x 4.65 in W x 5.8 in D. Ships at approximately 4 lbs packed.
