This is a ZAPI DUALAC2 series motor controller, rebranded and used by CLARK (a major manufacturer of forklifts and material handling equipment). It is a high-performance, programmable AC drive controller designed to power and control dual AC induction motors in electric industrial vehicles.
Key Specifications & Features
-
Model & Part Numbers:
-
Clark Model: FZ5035A
-
Clark Part Number: 8064706
-
Core Drive Unit: ZAPI DUALAC2 (specifically the POWER variant, indicating high current rating).
-
FSIP Number: 1232 (FSIP is a major remanufacturer of controllers; this is their cross-reference number).
-
-
Electrical Ratings:
-
Voltage: 36/48V DC nominal input. It is designed to operate on both 36-volt and 48-volt battery systems.
-
Current: The “FZ5035A” model code typically indicates a very high continuous current rating, likely in the 350 Amp range or higher, suitable for demanding applications like large forklifts.
-
-
Technology: DUALAC2 (AC Drive)
-
AC Control: Controls two separate 3-phase AC induction motors. This is common in forklifts where one motor drives the hydraulic pump for lifting/tilting, and another motor drives the traction system for movement.
-
Advantages: Offers high efficiency, excellent low-speed torque, regenerative braking, and requires less maintenance than older DC systems.
-
Programmability: The ZAPI DUALAC2 is highly programmable via PC software (ZAPI’s “Set & Go” or similar), allowing customization of acceleration curves, speed limits, braking behavior, and other vehicle parameters.
-
-
Application:
-
Primary Use: This controller is specifically designed for Clark electric forklifts and/or other Clark material handling equipment (e.g., pallet jacks, tow tractors) that use a dual AC motor configuration.
-
Function: It serves as the central “brain” and power regulator, taking input from the operator’s accelerator, direction selector, and hydraulic controls, and precisely delivering power to the traction and hydraulic motors.
