380V Elevator Small Machine Room Control Cabinet Power Supply
Cabinet
The Elevator Small Machine Room (SMR) Control Cabinet is a compact
and efficient control system designed for modern elevator
installations where space optimization is crucial. It integrates
advanced electrical and electronic components to manage the
elevator’s operation, safety, and communication functions.
Constructed from durable materials, the cabinet houses critical
components such as the inverter, controller, safety circuits, and
power supply units. Its modular design ensures easy maintenance and
scalability for different elevator configurations. The inverter
regulates motor speed, ensuring smooth starts, stops, and
energy-efficient operation, while the microprocessor-based
controller processes input signals from sensors, call buttons, and
safety devices to coordinate movements.
Safety features include overload protection, emergency stop
circuits, and fault diagnostics, compliant with international
standards like EN 81-20/50. The cabinet also supports remote
monitoring and connectivity for predictive maintenance.
Ideal for mid-rise buildings, the SMR Control Cabinet reduces the
machine room footprint without compromising performance, offering
reliability, energy savings, and quiet operation. Its user-friendly
interface simplifies troubleshooting, making it a preferred choice
for modern elevator systems.

FAQ
1. Are the elevator wire ropes durable?
The elevator wire rope has special provisions and requirements.
Configuration is not only for wire rope and rated load, but also
considered the size of the traction, as a result, the tensile
strength of wire rope is greater than the weight of the lift. The
safety factor is equipped with more than four wire rope. So it
won’t break at the same time.
2. Is it dangerous for power failure suddenly during the elevator
running?
If it occurs, the elevator will automatically stop due to the
electrical and mechanical safety device. In case of power
failure,elevator brakes will automatically taken. In addition, the
power supply departments such as planned outage, prior notice are
also operating.
3. Will us be hurt when it closed suddenly?
In the closing process, if people touch the hall door, the door of
elevator will automatically restart without any danger. With anti
clamping switch, once the gate touched, this switching action make
the elevator unable to be closed and even reopened. In addition,
closing force is also available here.
4. How the elevator running?
Elevators are operated with a counterweight wire rope through the
(tractor) traction drive, making ups and downs on the guide rail.
5. Is the escalator installation complicated?
We believe the functions of an escalator are not necessarily
proportional to the operation complexity. Therefore, escalators
designed by us apply an integrated structure, so that the equipment
is more precise and more efficient and allows easier and more
convenient commissioning.
6. Do you have any cerifications?
Yes, we do with ISO9001 / CCC / CE Certificates for u.
