Definitions
Maximum power: Maximum power drawn, resistance connecting is carried out at 360V, hence,
the power drawn has a maximum resistance value equal to 360.
Pulse power: maximum power dissipated by the resistor, this power can only be drawn for a
short time and in compliance with a certain cycle.
Permanent power (to 25°C) : mean power that can be dissipated on a permanent basis by the
resistor.
Maximum duration: maximum duration, in seconds, for which the pulse power can be required
(starting from cold); the resistor must be allowed to cool down before braking again.
Module losses: losses specific to the module, the value shown in the table is that obtained when
the module is used at maximum power.
Low-level consumption: consumption of the low-level power supplies in Watts.
