The Guardian SPMD/SPM Retrofit Kits replace the legacy power section in existing SPMD & SPM systems.
The module is 8RU high and contains two rectifier/controller power shelves incorporating up to 7 Guardian family high eff iciency hot-swap rectifier modules along with an ACX Advanced system controller plus an alarm module. A maximum total current of 375A N+1 is available. The rectifiers are internally fan cooled with speed control which is a function of load and temperature, keeping acoustic noise to a minimum.
The ACX Advanced controller monitors system parameters, controls rectifier output, and provides alarms for system failures. The controller is hot-pluggable for easy field replacement in case of failure. There are 2 LED alarm indicators which indicate failures, (RED) Alarm and (YELLOW) Message. A third green LED indicates the controller is working properly. As standard ten form-C relay outputs provide the alarms for remote use. Two digital inputs and outputs are also provided as well as an SD card with sufficient capacity for more than 20 years data logging.
The system can be programmed by means of a remote PC web page display. Communication is by Ethernet LAN with SNMPv3 including alarm trapping. It also has provision for temperature compensated charging of an external battery using a supplied TC probe. An LCD Display/Touchpad is included for local metering, status, and setup.
The Guardian AGM Retrofit Kit is compatible with UNIPOWER’s free PowCom™ software which offers local and remote management through an advanced Windows GUI.
