Product Description
CURTIS DC Motor Controller 1243-4322
Programmable, 24/36V 300A, Forklift & Pallet Truck Driving Motor Controller
The controller model P143-4322 could be used as the replacement of CURTIS controller model 1243-4220, 1243-4320 and other 1243 series 24V / 36V controller models (max current ≤ 300A).
We may also provide the full set of controller assemblage of P143-4322, including the throttle. For more information, please contact us.
For the buyer without CONTROLLER APPLYING EXPERIENCE, please consult your cart/motor dealer and read carefully the 1243 Controller Manual (PDF format) before making the purchase.
Overview:
CURTIS 1243 Generation 2 MultiMode™ controllers are separately excited motor speed controllers designed for use in a variety of small industrial vehicles and in material handling equipment. These programmable controllers are simple to install, efficient, and cost effective, while offering more features than the original 1243.
The 1243 GEN2 MultiMode™ controller provides smooth precise control of motor speed and torque. A full-bridge field control stage is combined with a half-bridge armature power stage to provide solid state motor reversing and full regenerative braking without additional relays or contactors. The controller's rugged IP53 housing and packaging are built to withstand shock and vibration. State-of-the-art surface mount logic board fabrication makes the 1243 GEN2 controller even more reliable than the original 1243. The 1243 GEN2 is fully programmable through the CURTIS Model 1313-4331 Handheld Programmer or 1314 PC Programming Station. In addition to configuration flexibility, the programmer provides diagnostic and test capability.
Appropriate throttles for use with the P143-4322 controller include:
- Type 1: 2-wire 5kΩ-0 throttles
- Type 2: 0-5V throttles, current source throttles, three-wire potentiometer throttles, and electronic throttles wired for singleended operation
- Type 3: 2-wire 0-5kΩ throttles
- Type 4: 0-5V and three-wire potentiometer throttles wired for wigwag operation
The last two digits of 1243 GEN2 model numbers are 20 or higher:
- 1243-4201, 1243-4202, and 1243-4301 are 1243 controllers
- 1243-4220, 1243-4221, and 1243-4320 are 1243 GEN2 controllers.
