Replacing CURTIS 1205M-6B403
Upgraded Version of 1205M-6B401 (Part Number: 17721701) & Fully Compatible
60/72V - 400A

The P125M-6B403 controller is a DC series winding motor speed controller, designed as the replacement of CURTIS 1205M-6B403 controller (and old CURTIS 1205M-6401 and 1205M-6B401 controllers).
Made by a Chinese manufacturer, the P125M-6B403 controller is fully compatible with CURTIS programming devices, and the quality had been approved by many vehicle makers. All parameters of P125M-6B403 are the same as its original version of CURTIS 1205M-6B403. So the buyer can take the CURTIS 1204M/05M/09/21M controller manual as its own manual.

Key Features:
Controller Model: P125M-6B403 (Replacement of CURTIS 1205M-6B403)
Norminal Battery Voltage (Volts): 60V / 72V (Two voltage settings are available. The voltage can be set to either 60 volts or 72 volts. By defaut, it is set as 72 volts.
The buyer should confirm with the seller the battery system voltage and the throttle type (0-5kΩ, 5k-0Ω or 0-5V). There is no extra cost for reprogramming the controller or other CURTIS programmable devices.
By defaut, we will the controller of setting of 72V / 400A / 0-5kΩ (Throttle Type = 0).

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
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 Programming Station
Rugged anodized aluminum extruded housing meets IP65 environmental sealing standards for use in harsh environments.
