MOD-BA module is DIN-rail mountable active redundancy module from Leuze electronic.
With the help of the redundancy module, two power supply units of the same type on the
output side are decoupled 100% from each other.

(1) General
The device may be installed only by trained and qualified personnel. MOD-BA module is
maintenance-free. Repairs can only be done by the manufacturer.
Balancing is achieved when input current is > 2 x 0,5 A and input voltage difference is
between 0 ... 300 mV 0% / -15% (2 x 10 A) or 0 ... 200 mV 0% / -15% (2 x 20 A).
Intelligent technology increases system efficiency in comparison to traditional technology
with diode. Current balancing technology makes possible to increase lifetime of power
supplies. If overheated balancing is disabled but unit continues to operate.
For high redundancy we recommend three-phase power supplies.
Only for use in pollution degree 2 environments.

(4) Location [13]
MOD-BA module is cooled by natural convection. It is important to maintain clearance
to other components as much as possible to ensure best performance and long term
stability. Top and bottom clearances should be 50 mm at minimum. The ambient
temperature should be measured on the underside of the unit. There will be an increase
of 25°C at the top. If natural convection is restricted, forced cooling should be used.
Mounting should comply with EN 60950-1 point 4.7 and 4.6.1. Protection class of the
case IP20 (EN 60529).
(5) Mounting [12]
The rail should be fixed solidly so that it cannot twist when mounting or removing the
unit. Mounting instructions [10], Removing instructions [11].
