RT7-120VDC/6kW Specification
The RT7-120VDC/6kW is a 3 phase, active power
factor corrected, switched mode rectifier (SMR)
module designed to provide up to 6kW of output
power (60A limit) into a 120VDC nominal system.
This rectifier is primarily used in conjunction with a
battery to provide an uninterruptible or standby DC
power system, or used as a battery charger. Up to
20 rectifiers can fit in a rack and up to 225 rectifiers
can be configured as a system using one control
and supervisory unit (CSU). The system can be
monitored and controlled remotely using WinCSU
software (see CSU specification for more details).
Illustrated is a single rectifier module.

Output Current (A)
*60A current limit automatically reduces by 0.6A/°C for heatsink
temperatures above 60°C.
Voltage Withstand Test:
1000VAC output to chassis for 1 minute;
(1500VDC 100% testing on production units);
Soft start circuit prevents surges when connection
is made to a live DC bus;
Overvoltage - only faulty unit shuts down;
Overcurrent - can sustain short circuit at output
terminals indefinitely. Output current starts folding
back when output voltage drops below 70V to less
than 20A at zero terminal voltage;
Over-temperature - gradual reduction of power limit
if heatsink temperature exceeds pre-set limit;
Remote Controls
Equalise Mode:
Equalise mode is initiated by a signal from the
CSU. In case of loss of communication with the
controller the SMR will default to the Float mode;
Rectifier Inhibit:
Rectifiers can be inhibited by a signal from a
remote WinCSU terminal, transmitted via the CSU;

External Digital Voltage Control (EDVC):
The
CSU
uses
the
optically
coupled
communications lines to digitally control rectifier
Float and Equalise voltages over a limited voltage
range in order to adjust battery voltage for
temperature and voltage drop in DC bus, limit the
maximum battery recharging current and to
achieve active current sharing;
