New 36V/48V 1205M-5603 500A DC Motor Speed Controller For CURTIS. 1205M-5603 is the newest. 48V / 500A / 0-5k? (new generation of 1204M / 1205M controller, upgraded 1205M-5601, with newly added J5 terminal to provide reverse signal, supporting more throttle types). Norminal Battery Voltage (Volts): 36/48 Two voltage settings are available. The voltage can be set to either 36 volts or 48 volts. By defaut, it is set as 48 volts, with an allowable working range 33-48V. If it is set as 36 volts, the allowable working range is 25-36V. By defaut, we will the controller of setting of 48V / 500A / 0-5k? . 5 Second Boost Current (amps): 600. Plug Braking (A2 Busbar): Yes. Important information: 1205M-5603 is the upgraded version of 1205M-5601 controller. Nominal input voltage: 36/48 V 1205M-5601 has two available battery voltage settings. PWM operating frequency: 15 kHz. Electrical isolation to heatsink min. KSI input current (no contactors engaged). Status LED output current max. Throttle type: 2-wire 0 – 5k? , 2-wire 5k? – 0, or 0 – 5V. Storage ambient temperature range: -40°C to 85°C (-40°F to 185°F). Range: -40°C to 50°C (-40°F to 122°F). Weight: 2.7 kg. Dimensions (L× W×H) : 199 × 146 × 77 mm. Regulatory compliance: Safety – Designed to the requirements of EN 1175; EMC – Designed to the requirements of EN 12895 and EN 61000. By defaut, we will the controller of setting of 48V / 500A / 0-5k? (Throttle Type = “0”). Ten throttle types can be used with 1204M-5203. Type 0: 2-wire potentiometer, 0-5k? Type 1: 2-wire potentiometer, 5k? -0. Type 2: single-ended 0-5V input. Type 3: 2-wire potentiometer, 4.6k? -0. Type 4: 2-wire potentiometer, 5.5k? -0. Type 5: 2-wire potentiometer, 1k? -0. Type 6: ITS input. Type 7: single-ended 6.3-10.6 V input. Type 8: single-ended 6-12 V input. Type 9: single-ended 3-wire potentiometer, 0-5k? Attention: the CURTIS 1205M-5603 could be replacement for many old 1204/1205 controller, for example 1205-202, 1205-201 or other models. High-frequency switching and ultra-low voltage drops provide high efficiency and silent operation. Simple mounting and wiring with push-on connectors for control signals and plated solid copper buses for power connections. Compatible with either a two-wire potentiometer or a voltage throttle. Throttle fault protection circuitry disables controller if throttle wires become open. High pedal disable feature prevents controller operation if key is turned on while throttle is applied. Plug braking diode internal to controller. Thermal protection and compensation circuit provides constant curr. Ent limit over operating range and during under/over temperature cutback; no sudden loss of power under any thermal conditions. Undervoltage cutback function protects against low battery voltage, including low voltage caused by external loads. Rugged anodized aluminum extruded housing meets IP65 environmental sealing standards for use in harsh environments. 1 x Motor Controller. Thank you for your support.
