{"id":"automationdirect-gs4-45p0","model_id":"GS4-45P0","name":"AutomationDirect GS4-45P0","summary":"The GS4-45P0 is a DURApulse GS4 series AC variable frequency drive rated 5 hp with a 3-phase 460 VAC input and output. It controls 3-phase induction motors in either sensorless vector control (SVC) or V/Hz mode and has integrated dynamic braking. It is a NEMA 1, IP20, A-frame unit mounted on a panel or wall, with an RS-485 port, embedded ladder programming and optional EtherNet/IP and Modbus TCP cards.","study_notes":["Rated 5 hp with 3-phase input; amperage rating 8.1 A, variable torque amperage rating 9 A.","Control mode selectable between SVC (sensorless vector control) and V/Hz.","Onboard I/O: 8 discrete inputs at 24 VDC (sinking/sourcing), 4 discrete outputs at 240 VAC and 48 VDC, 3 analog inputs and 2 analog outputs.","Discrete outputs include 2 Form C (SPDT) relays; load current 3 A/point relay, 50 mA/point discrete.","Analog input resolution 11-bit (0–20 mA, 4–20 mA, ±10 VDC); analog output resolution 10-bit (0–20 mA, 4–20 mA, 0–10 VDC).","Carrier frequency range 2–15 kHz; output frequency range 0.1–599 Hz.","Communication port is RS-485 (RJ12) at up to 115.2k baud; port protocols listed are Modbus RTU, Modbus ASCII and BACnet.","Optional EtherNet/IP and Modbus TCP cards are available; these are add-on cards, not built into the base drive.","Embedded drive PLC is programmed in ladder using GSLOGIC software; GSOFT2 is the configuration software.","No integrated EMI filter; reverse capability is built in; not internally bypassed.","Connector type is screw terminals; intended for use with 3-phase induction motors.","Shipping weight as stated on the item page is 7.5 lb."],"safety_notes":["Safe Torque Off (STO) is built-in.","A user-supplied external fuse is required.","Operating temperature rating -10 to +50 °C.","Enclosure type NEMA 1 with IP20 rating.","UL Listed, file # E198015; UL Recognized and UL Hazardous files listed as none.","CE marked; RoHS status yes; EU REACH document available; CSA file listed as none."],"sources":[{"url":"https://www.automationdirect.com/adc/shopping/catalog/drives_-a-_soft_starters/ac_variable_frequency_drives_(vfd)/high-performance_vfds/gs4-45p0","title":"DURApulse AC High-performance Drive: 460 VAC, 5hp with 3-phase input, (VFD) (PN# GS4-45P0) | AutomationDirect","accessed":"2026-10-26"},{"url":"https://cdn.automationdirect.com/static/specs/cutsheet/GS4-45P0_cutsheet.pdf","title":"GS4 45P0 cutsheet","accessed":"2026-10-26"}],"verification":{"status":"source_checked","checked_at":"2026-10-26","values":8,"method":"llm_source_check"},"updated_at":"2026-10-26","type":"hardware","spec":{"category":"vfd","manufacturer":"automationdirect","controllers":[],"supply_voltage":"460 VAC","frame_size":"A","ip_rating":"IP20","operating_temp_min_c":-10,"operating_temp_max_c":50,"joints":[],"protocols":["modbus-rtu","modbus-ascii"],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/automationdirect-gs4-45p0","license":"https://creativecommons.org/licenses/by/4.0/"}
