{"id":"automationdirect-gs23-4025","model_id":"GS23-4025","name":"AutomationDirect GS23-4025","summary":"The GS23-4025 is an enclosed DURApulse GS20 series general-purpose AC variable frequency drive. It takes a 460 VAC three-phase input rated 25 hp and drives three-phase induction or permanent magnet AC motors using SVC, V/Hz, FOC or torque control modes. It provides an RS-485 port with Modbus RTU/ASCII slave support, a USB B port, analog and discrete I/O, and integrated dynamic braking.","study_notes":["Rated 25 hp with 3-phase input; 38 A rated current, 41.5 A in variable torque duty.","Control modes: SVC (sensorless vector control), V/Hz, FOC or torque mode.","Output frequency range 0.1–599 Hz; carrier frequency range 2–15 kHz.","Communication: (1) RS-485 (RJ45) and (1) USB B, speeds up to 115.2k baud, Modbus RTU Slave and Modbus ASCII Slave.","I/O: 2 analog inputs (0–20 mA / 4–20 mA, +/-10 VDC, 10-bit and 12-bit resolution), 1 analog output (0–20 mA / 4–20 mA, 0–10 VDC, 10-bit), 7 discrete inputs at 24 VDC sinking/sourcing, 3 discrete outputs (240 VAC and 48 VDC, relay/sinking/sourcing) including (1) Form C (SPDT) relay.","Load current 3 A per point for the relay output and 50 mA per point for discrete outputs; a user-supplied external fuse is required.","Integrated dynamic braking; the drive is not internally bypassed and has no integrated EMI filter.","Programmed in ladder; spring clamp terminals; keypad GS20A-KPD supplied attached to the drive.","Optional EtherNet/IP and Modbus TCP card available (communication card, not native to the drive).","Mounting is panel or wall; frame size F; item shipping weight 16.6 lb.","Brand DURApulse, series GS20, controller type general purpose."],"safety_notes":["Safe Torque Off (STO) is built in.","Enclosure IP rating is IP20, so the drive must be installed in a suitable enclosure environment.","Operating temperature rating is -20 to +50 deg C.","UL Listed, file # E198015; UL Recognized and UL Hazardous: none. CSA file: none.","RoHS status: Yes (see CE doc); CE declarations available; EU REACH document available."],"sources":[{"url":"https://www.automationdirect.com/adc/shopping/catalog/drives_-a-_soft_starters/ac_variable_frequency_drives_(vfd)/general_purpose_vfds/gs23-4025","title":"DURApulse AC General Purpose Drive: 460 VAC, 25hp with 3-phase input, (VFD) (PN# GS23-4025) | AutomationDirect","accessed":"2026-10-26"},{"url":"https://cdn.automationdirect.com/static/specs/cutsheet/GS23-4025_cutsheet.pdf","title":"GS23 4025 cutsheet","accessed":"2026-10-26"}],"verification":{"status":"source_checked","checked_at":"2026-10-26","values":9,"method":"llm_source_check"},"updated_at":"2026-10-26","type":"hardware","spec":{"category":"vfd","manufacturer":"automationdirect","controllers":[],"weight_kg":7.53,"supply_voltage":"460 VAC","frame_size":"F","ip_rating":"IP20","operating_temp_min_c":-20,"operating_temp_max_c":50,"joints":[],"protocols":["modbus-rtu","modbus-ascii"],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/automationdirect-gs23-4025","license":"https://creativecommons.org/licenses/by/4.0/"}
