New 36V/48V 125M-5603 500A DC Motor Speed Controller replacing CURTIS 1205M-5603

Description

36V/48V 125M-5603 500A DC Motor Speed Controller replacing CURTIS 1205M-5603
DC Motor Speed Controller
Upgraded Version of 125M-5601
36/48V 500A
KEY FEATURES
Model: 125M-5603 (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).
The buyer should confirm with the seller the battery system voltage and the throttle type (0-5kΩ, 5k-0Ω or 0-5V).
By defaut, we will the controller of setting of 48V / 500A / 0-5kΩ (Throttle Type = "0").
Ten throttle types can be used with 1204M-5203:
Type 0: 2-wire potentiometer, 0–5kΩ
Type 1: 2-wire potentiometer, 5kΩ–0
Type 2: single-ended 0–5V input
Type 3: 2-wire potentiometer, 4.6kΩ–0
Type 4: 2-wire potentiometer, 5.5kΩ–0
Type 5: 2-wire potentiometer, 1kΩ–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, 0–5kΩ
For the buyer without CONTROLLER APPLYING EXPERIENCE, please consult your cart/motor dealer and read carefully the CURTIS 1204M/05M Controller manual before making the purchase.
Main Features:
1 Minute Current Rating (amps): 500
5 Minute Current Rating (amps): 350
1 Hour Current Rating (amps): 200
Plug Braking (A2 Busbar): Yes
(Attention: the CURTIS 1205M-5603 could be replacement for many old 1204/1205 controller, for example 1205-202, 1205-201 or other models. For more details of replacement, please feel free to contact us.

Wiring Diagram:
By default, the J5 terminal of P124M-4201 controller is not activated. The controller wiring is same to the old 1204M controllers without J5 terminal.
Features include:
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 current 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.
Easily programmable through the Curtis Model 1313-4401 Handhold Programmer or 1314 PC groramming station
Rugged anodized aluminum extruded housing meets IP65 environmental sealing standards for use in harsh environments.
