Controlled Speed launches powerful, low cost motor control units for stair lifts

Controlled Speed Engineering (CSE) has announced its latest motor control products targeted at the stair lift market. The MS 1 low cost stair lift control system and the MS 2 ancillary interface board provide complete flexibility for stair lift manufacturers to select the right product for their requirements, and use advanced motor control technology to enable smooth and efficient operation.



The MS 1 provides core motor control functionality at the heart of a modular system, and is specifically designed for stair lifts. For example, it includes inputs that enable the lift to be automatically slowed through an inside curve.

Features integrated on the MS 1 board include four-quadrant control, a dual redundant safety system, and 3 stage battery management. It also provides a short circuit-proof loom interface, and an 8-way DIP Switch for customization such as left hand / right hand selection.

To add extra features, stair lift manufacturers can add the MS 2 ancillary interface, which allows Controlled Speed’s CSE 126 ancillary controller to be used with the MS 1.The CSE 126 provides advanced stair lift control functions such as powered seat swivel, powered hinge and powered platform control. When used with the CSE 127 display board, it also provides a full fault diagnostic analysis. The MS 1 can also be linked to a PC with the CSE 128 connection lead for easy diagnostics.

The MS 1 can act as the central control board in a modular system, including other interfaces and units from Controlled Speed’s industry-leading stair lift range. This includes infra red transmit and receive boards, an innovative GSM/GPRS unit for remote diagnostics, and a Bluetooth interface for diagnostics via a PDA.

The MS 1 has a wide input voltage range of 12-35V with a 16V under voltage lock out. It provides 30A run current and a 40A current limit. It has a low sleep current of only 15mA for long battery life.

All of Controlled Speed’s motor control products meet the requirements of both BS 5776:1996 and ISO 9386-2 for stair lifts.
