KR-48100 Rectifier Module
Topaz KR-48100 is a compact 2U high by 19 inch wide rectifier module and up to 20
units, equivalent to 2,000A can be can be constructed in a single rack. Power systems of
up to 11,000A capacity can be constructed using multiple racks. It features unity power
factor, typical efficiency greater than 91%, a wide AC input range of 187 - 275Vac with
forced air cooling in an ambient of 0 - 50°C.

| Alarms |
AC on, SMR off and SMR alarm present indicated on front panel. Other
alarms and status are displayed on the alphanumeric LCD display. |
| Remote Alarms |
All alarm states defined above are transmitted to the MiniCSU |
|
| Remote Controls
|
| Equalise Mode |
Equalise Mode is initiated by a signal from the MiniCSU. |
| External Voltage Control (EVC) |
Optically coupled PWM signal used to control rectifier Float and
Equalise voltage over a limited range to optimally adjust battery voltage for temperature
and voltage drop in DC bus, limit the maximum battery recharging current and achieve
active current sharing. See MiniCSU specification. |
| Rectifier Inhibit |
Rectifier can be inhibited by a signal from a remote computer,
transmitted via the MiniCSU. |
