DUSH-series UPS-systems from TDK-Lambda - Power
960 W programmable DIN-rail DC-UPS for mission-critical applications
TDK-Lambda introduces the DUSH series UPS systems housed in a compact enclosure for DIN-rail mounting.
The DUSH series provides emergency power in case of power failure. Under normal conditions, the load is powered by the power supply connected to the input. The DUSH series also manages the charging of the connected battery. In the event of a power interruption, the DUSH module maintains a regulated output voltage, using the battery as the power source for the load.
The DUSH series can operate with an input voltage of 10 to 60 V and can be programmed to deliver a regulated output of 10 to 58 V, with a nominal output current of 20 A. Additionally, there is an unregulated auxiliary output of 5 A available (model with suffix -0M). Multiple battery technologies are supported, including lead, nickel, lithium, and supercapacitors, up to a capacity of 1000 Ah.
An integrated DC-DC buck/boost converter decouples the battery from the load voltage. The DUSH module maintains the condition of the battery by preventing deep discharge, enabling temperature-compensated charging, and monitoring internal resistance.
The front panel features a user interface in the form of a 1.5-inch graphical LCD color display and four control buttons (model with suffix -0M).
The DUSH series offers multiple interfaces and signals, including two configurable alarm relays, an isolated remote on/off contact, status LEDs, and an input for the battery temperature sensor. There is a Mini USB-B or RS485 port (Modbus) for monitoring and programming. The Control and Monitoring Center (PowerCMC) software assists with commissioning and maintenance, keeps an alarm log, and provides real-time status data for monitoring.
