Systems with a model number beginning with PSX24 can hold three rectifier modules and have
a maximum power output of 2.4kW, producing a maximum current output of 44.4A at 54Vdc.
The system is intended to be a complete power system in a box, so no connections need to be
made internally. AC connection is via rear exiting lead with all the DC (Load and Battery)
connections are made at the front of the unit. Alarm connections are accessible from the front.
The system is designed to be extremely simple to install and set up.
The following is a summary of the system:
-
Overall size is 483mm wide (19” standard mounting) x 44.5mm high (1U) x 280mm deep
(within ETSI specification)
-
Optional ETSI mounting tabs included
-
Up to 3* RM848 series rectifiers - may be packaged separately
-
SM3x supervisory module (fully integrated in the system)
-
Battery Low Voltage Disconnect fitted as standard (80A rating).
-
Up to 2*x 30A Battery Circuit Breaker, this may be specified as different values (from 2A to
30A) at time of order.
-
Up to 4*x Load Circuit Breaker, this may be specified as different values (from 2A to 30A) at
time of order. If only one Battery Circuit Breaker is fitted, a 5
th
load breaker can be specified
at time of order.
-
System weight is approximately 3.6kg without rectifiers, and 5.6kg with three rectifiers fitted.
-
Single phase lead supplied for input termination (phase, neutral and earth)
-
Front or rear cable access
*values shown are maximum values and depend upon model selected. Please see model
numbers and descriptions in the appendix of this manual.
Note:
This system is supplied with the AC and DC earths connected. The standard system
(+ve earth system) output has the DC Common (earth connection) in the positive side
of the circuit.
The user selectable, positive/negative earth system has the DC Common (earth
connection) in the negative side of the circuit, but can be changed by following the
instructions in the DC earthing section of this manual.
The earth link can be completely removed from the system to isolate earths. Please
see the DC earthing section of the manual.
