| Monitoring | |
|---|---|
| Current | Monitored on MiniCSU display. Accuracy ± 1% at full load. Optional bar-graph display. |
| Voltage | System voltage displayed on MiniCSU's alpha-numeric display. Accuracy ± 0.5% at full load. |
| Alarms | SMR normal, SMR alarm present and SMR shutdown indicated on front panel. Other alarms and status displayed on 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. |
| Environmental | |
| Cooling | Forced air cooling. Fan speed control |
| Temperature | Operating range: 0° to 50° C. |
| Humidity | 0% to 90% non-condensing. |
| Mechanical | |
| Noise | < 55 dBA ( A Weighted). |
| Dimensions | Height 267 mm (6 U). Width 89 mm. Depth 300 mm. |
| Mass | < 6 kg. |
| Magazine Size | The KR-Mag5 Magazine holds 5 Rectifiers across a 19" rack. One row of Rectifiers occupies 9U of rack height, 3U occupied by fan unit. The Magazine fits a rack depth of 400mm or greater. |
| Connections | Input, Output & a multi-purpose connector is mounted on the back of the Rectifier Module with a matching connector at the back of the Magazine. Mating of connectors occurs when the Rectifier is plugged into the Magazine.The Rectifier is mechanically latched to ensure a reliable connection. |
