Picture :
The ‘E’ difference: a significant enhancement to the CURTIS AC family, The ‘E’ models utilize a powerful dual-microprocessor logic architecture to provide improved performance and surpass the requirements of the latest international functional safety standards. CURTIS Models 1236E and 1238E provide advanced control of AC induction motors performing on-vehicle traction drive or hydraulic pump duties. They offer vehicle developers a highly cost-effective combination of power, performance and functionality. Designed primarily for use on medium to large material handling vehicles such as counterbalance or warehouse trucks. The Model 1236E is equally suitable for industrial utility vehicles. The larger Model 1238E is also intended for use on all heavy-duty applications such as Tow Tractors and Airport Ground Support Equipment (GSE).
