Features
Four Functions in One Integrated Unit
The SB50W provides instantaneous stop, forward/reverse
operation, electromagnetic brake control and thermal protector
open detection functions
✽
.
Thermal protector open detection function
(Available only when combined with a motor having a built-in thermal protector) When the
motor’s thermal protector (overheat protection device) is activated, the SB50W outputs
an alarm signal and automatically cuts the power supply to the motor. The motor will not
restart by itself, even after the temperature drops and the thermal protector recovers, until
the power is cycled. Possible to reset the alarm through external signals.
Wide Voltage Range of 100 to 230 VAC
The SB50W covers a single-phase voltage range of 100 to 230
VAC  10%, 50/60 Hz, accommodating all of the world's key
voltage specifications.
Conforms to Safety Standards
This is the world first brake pack which conforms to safety
standards. The CE marking is used in accordance with the EMC
directives and low voltage directives.

Supports Motors with 1 to 90 W Output
The SB50W can be used with induction, reversible, electromagnetic
brake and watertight, dust-resistant motors with an output range of 1
to 90 W.
Switchable Sink/Source Logic
Select the sink mode or source mode for the input/output circuit.
You can change the setting at any time.

The SB50W provides instantaneous stop, forward/
reverse operation, electromagnetic brake control
and thermal protector open detection functions
integrated into one unit. These brake packs can
sense when the thermal protector is opened, further
ensuring the safety of your equipment.
