{"id":"automationdirect-gs33-2050","model_id":"GS33-2050","name":"AutomationDirect GS33-2050","summary":"The GS33-2050 is an enclosed DURApulse GS30 series AC variable frequency drive rated 50 hp on a 230 VAC three-phase input. It controls three-phase induction and permanent magnet AC motors using SVC, V/Hz, FOC, encoder or torque control modes, with a 0.1 to 599 Hz output frequency range and a 2 to 15 kHz carrier frequency. Setup, monitoring and embedded ladder logic programming are handled through RS-485 (Modbus RTU/ASCII slave) or USB B connections.","study_notes":["Rated 50 hp with 3-phase input; rated current 146 A, variable torque rating 160 A.","Control modes: SVC, V/Hz, FOC, encoder or torque.","Output frequency range 0.1-599 Hz; carrier frequency range 2-15 kHz.","Communication: (1) RS-485 (RJ45) and (1) USB B port, up to 115.2k baud, Modbus RTU Slave and Modbus ASCII Slave.","On-board I/O: 7 discrete inputs (24 VDC sinking/sourcing), 3 discrete outputs (relay/sinking/sourcing, one Form C SPDT relay), 2 analog inputs (12-bit), 1 analog output (10-bit).","Analog input ranges 0-20 mA and 4-20 mA, +/-10 VDC; analog output ranges 0-20 mA and 4-20 mA, 0-10 VDC.","Programming language: ladder (embedded drive PLC); configuration via GSOFT2 software, programming via GSLOGIC.","External dynamic braking unit required; integrated EMI filter: no.","Enclosure is IP20, frame size I, panel or wall mounting.","Shipping weight stated as 94 lb; country of origin India.","Optional communication, encoder and I/O modules available.","Input signals: 4-20 mA, voltage, potentiometer or pulse train; output type PWM."],"safety_notes":["Built-in Safe Torque Off (STO) function.","User-supplied external fuse required.","UL Listed File # E198015; RoHS status: Yes (see CE declaration).","Operating temperature range -20 to +50 deg C.","Meets IP20 enclosure rating only; not protected against water ingress."],"sources":[{"url":"https://www.automationdirect.com/adc/shopping/catalog/drives_-a-_soft_starters/ac_variable_frequency_drives_(vfd)/high-performance_vfds/gs33-2050","title":"DURApulse AC High-performance Drive: 230 VAC, 50hp with 3-phase input, (VFD) (PN# GS33-2050) | AutomationDirect","accessed":"2026-10-26"},{"url":"https://cdn.automationdirect.com/static/specs/cutsheet/GS33-2050_cutsheet.pdf","title":"GS33 2050 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":[],"supply_voltage":"230 VAC, 3-phase","frame_size":"I","output_type":"PWM output","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-gs33-2050","license":"https://creativecommons.org/licenses/by/4.0/"}
