3-Wire 0-5 Potentiometer Throttle

Model EFP-005, with internal throttle switch

Overview:

The foot pedal throttle EFP-005 is a 0-5KΩ potentiometer throttle (3-wire pot throttle), is widely used in forklift (typical application: HANGCHA), golf cart and other electric mobility vehicles.

We supply also the similar throttle model EFP-005Y with waterproof connector, which is used as the foot pedal accelerator for MARSHELL passenger / sightseeing vehicles.

Specifications:

• The foot pedal could be installed at both ends of rotating shaft
• Signal output: 0-5KΩ  ± 0.1KΩ (BI potentiometer P270-033B)
• Solid metal case, ingress protection: IP55
• Installation kit is included: bolts, nuts and washes
• Mating connector is included
• Net weight: 1.20 kg (with installation kit and mating connector)

Key Features:

• Model: EFP-005, working with CURTIS 1204M-4201 Series Motor Controller, CURTIS 1268-5403 SepEx Motor Controller and other CURTIS controllers
• Switch on/off signal: 0V - power supply voltage
• Operation temperature range: -55℃ –120℃
• Storage temperature range: -40°C - 80°C
• Ingress protection: IP55
• Mechnical lifespan: 1,000,000 times
• Installation kit is included: bolts, nuts and washes
• Mating connector is included
• Mechnical lifespan: 1,000,000 times

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 EFP-005, 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.
