Monitoring Control Unit with OLED Display
The MCU0x48M4-OLED is a microcontroller-based monitoring system designed for telecommunications power systems using 300W and 1000W rectifiers. It enables the monitoring and control of up to 4 rectifiers (up to 9 when integrated with the COMPAS platform), one battery string, and power distribution within a 1U to 2U power shelf, depending on the number of rectifiers installed.
This controller is a hot-pluggable, hot-swappable unit that fits into a 1U slot alongside the rectifier modules. It integrates COMPAS, providing advanced monitoring capabilities via Ethernet or USB.
Additionally, it supports interoperability with CAN bus-connected peripherals and equipment, such as cabinet security systems and environmental management devices.
Highlights
- Monitors up to 4 rectifiers — scalable to 9 when integrated with the COMPAS platform
- Hot-pluggable, hot-swappable — fits into a 1U slot alongside rectifier modules, no downtime for replacement
- OLED front display — shows output voltage, battery charge current, rectifier current, IP address, relay status, and LVD status directly on the unit
- Battery management — current limitation, temperature compensation, battery test, and capacity estimation
- Wide operating range — -40°C to 70°C, suited for outdoor and harsh cabinet environments
- Flexible connectivity — Ethernet, USB, and CAN bus, with configurable DIP switches for different rectifier module compatibility (ECOR0348TN, ECOR1048TN, or CDCWI1048TN)
- Customizable — specific configuration, Python scripting, and specific alarming when needed

FAQ
It's a monitoring and control unit for telecom power systems, managing up to 4 rectifiers (up to 9 with COMPAS), a battery string, and power distribution in a 1U or 2U shelf, such as the ACE102, ACE104, CAPTIN 1000BW, or CAPTIN 300FA.
It displays output voltage, battery charge current, rectifier current, the unit's IP address, relay status, and LVD (low voltage disconnect) status, directly on the front panel without needing a separate monitoring session.
Yes. It's a hot-pluggable, hot-swappable unit that fits into a 1U slot alongside the rectifier modules, so it can be replaced without interrupting power to the load.
