Manual Brake Energy Converter

Manual Brake Energy Converter
Version 0.4
Edition January 2016
General
The Brake Energy Converter (BEC) is a hardware
device to convert Back Electromagnetic Force
(Back-EMF) energy into heat during motor
deceleration. An internal voltage sense circuit
ensures that the output voltage does not increase
about 10 percent over the input voltage. With this
device, XENAX® servo controllers are protected
against overvoltage in high-speed applications.
The protection only occurs on the PW lines. No
protection on LG lines.
For UL-conformity, the XENAX® servo
controllers need to be used with the BEC to
guarantee voltage levels during dynamic
braking within DVC A Levels.

Vertical
orientation
>20mm
For a series mounting the distance between
the devices XENAX® to Brake Energy
Converter® has to be at least 20mm,
XENAX® to XENAX® has to be at least 10mm
and the distance to the floor has to be at least
40mm.
We recommend mounting the devices in
vertical orientation to ensure a good cooling air
circulation.

These products are intended for operation within
circuits not connected directly to the supply mains
(galvanically isolated from the supply).
The XENAX® Servocontroller/s need to be used with
the Brake Energy Converter to stay within the
36 DVC A Limits
Integral solid state short circuit protection does not
provide branch circuit protection. Branch circuit
protection must be provided in accordance with the
National Electrical Code and any additional local
codes.
For Canada (ENG): Integral solid state short circuit
protection does not provide branch circuit protection.
Branch circuit protection must be provided in
accordance with the Canadian Electrical Code, Part I.
For Canada (F): Des protections intégrées, à relais
statique, contre les court circuits, ne protègent pas
contre les circuits de dérivation. Une protection
contre les circuits de dérivation doit être fournie
conformément au code canadien de l’électricité,
