Replaces CURTIS 1205M-6B403
Upgraded version of 1205M-6B401 (part number: 17721701) and fully compatible
60/72V - 400A
The P125M-6B403 controller is a DC series winding motor speed controller, designed as a replacement for the CURTIS 1205M-6B403 controller (and old CURTIS 1205M-6401 and 1205M-6B401 controllers).
Made by a Chinese manufacturer, the P125M-6B403 control unit is fully compatible with CURTIS programming units, and the quality had been approved by many vehicle manufacturers. All the parameters of P125M-6B403 are the same as the original version of CURTIS 1205M-6B403. So the buyer can take the CURTIS 1204M/05M/09/21M control manual as their own manual.
KEY FEATURES:
Control model: P125M-6B403 (replacement of CURTIS 1205M-6B403)
Normal Battery Voltage (Volts): 60V / 72V (Two voltage settings are available. The voltage can be set to either 60 volts or 72 volts. By default, it is set to 72 volts.
Buyer should confirm with seller battery system voltage and throttle type (0-5kΩ, 5k-0Ω or 0-5V). There is no additional charge for reprogramming the controller or other programmable CURTIS devices.
By default, we will set the regulator to 72V / 400A / 0-5kΩ (Throttle Type = 0).
1 minute current rating (amperes): 400
5 minute current rating (amperes): 275
1 hour current rating (amperes): 175
Plug braking (A2 busbar): Yes
Ten throttle types can be used with the P125M-6B403:
Type 0: 2-wire potentiometer, 0–5kΩ
Type 1: 2-wire potentiometer, 5kΩ–0
Type 2: single-sided 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-sided 6.3–10.6 V input
Type 8: single-sided 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 quiet operation.
Easy assembly 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 protection circuits disable the controller if the throttle cables become open.
The high pedal disable feature prevents the controller from operating if the key is turned on while the throttle is on.
Connect the brake diode internally in the control unit.
Thermal protection and compensation circuitry provides constant current limit over the operating range and during under/over temperature drop; no sudden power loss under any thermal conditions.
Undervoltage reduction function protects against low battery voltage, including low voltage caused by external load.
Easily programmable through Curtis Model 1313-4401 Handheld Programmer or 1314 PC Programming Station
Rugged anodized aluminum extruded housing meets IP65 environmental sealing standards for use in harsh environments.
