3-Wire 0-5KΩ Potentiometer Throttle

Typical application: Marshell / Dongyu / Hasen / Langqing / Wosen golf carts & utility vehicles

Installation Kit & Mating Connector

Overview:

The foot pedal throttles JSQD-DWK-003HB are equipped with a mating connector (TE 350781-1), widely used as the accelerator of electric mobility and sportive carts (typical application: Marshell golf cart).

We supply also the similar throttle model JSQD-DWK-003D which is typically used in golf cart of EAGLE (EG-EV) brand.

As the upgraded version of JSQD-DWK-003, the new 3-wire 0-5K potentiometer throttle JSQD-DWK-003HB is used as the speed signal feeding device for motor speed controllers.

Trick: when it is necessary, the throttle JSQD-DWK-003HB can also be used as 2-wire 0-5K rheostat throttle, by choosing the Pot-Low terminal and Wiper wire.

Specifications:

• Product Name: electric vehicle accelerator assembly
• Model: JSQD-DWK-003HB
• Throttle type: 3-wire 0-5KΩ potentiometer
• Could be installed at both ends of throttle rotation shaft
• Double-return-spring design, assuring the initial neutral output (0Ω)
• Solid metal case, ingress protection: IP65
• Mechnical lifespan: 1,000,000 times
• Installation kit is included: bolts, nuts and washes
• 6-Pin water proof mating connector is included
• Operation temperature range: -20°C ~ 50°C
• Storage temperature range: -40°C ~ 80°C
• Net weight: 1.05 kg (with installation kit and mating connector)
• Package weight: about 1.55 kg

About the throttle switch:

Most electric vehicle throttles have a throttle switch. Depending on the application requirement, the throttle switch can be used for different purposes:

• Main contactor control: feeding power to main contactor's control coil.
• Forward / Reverse DC contactor interlock: feeding power to F / R switch through the throttle switch. The F / R contactor will only be activated when the throttle switch is "ON" (for avoiding accidental vehicle movement in case that the F / R switch is not at neutral position when key switch is turned on).
• Lifting / Lowering interlock: when forklift is in accelerating mode, the lifting or lowering function will be inhibited, for avoiding unsafe operation.
• Accelating alarm: sending signal to a display device (for example a lamp) for showing the accelerating status of vehicle.
• Etc.

For 0-5KΩ throttle model JSQD-DWK-003HB, you may choose a power source of variable DC voltage to control other devices through its internal switch. For example, your vehicle battery voltage is 48V, but you have a forward / reverse contactor of control coil rated for 12VDC, then you may use a 48V to 12V DC-DC converter to feed the 12VDC power to F / R switch through the throttle switch, for controlling the F / R contactor.

Caution: we don't recommend to apply a voltage which is higher than the voltage rate of main power source (vehicle battery) to the throttle switch.
