Outdoor IP65 Power & Backup System: 1-3kW

Multidirectional Converter


Wide temperature range



Remote Monitoring







HT1KWMP is an IP65 multidirectional power converter that can power 48Vdc, 230Vac loads and charge batteries at the same time. It was specially designed and manufactured for outdoor, high-temperature, and remote applications requiring high reliability, efficiency, and compliance with military specifications for shock and vibration and electromagnetic interference (MIL-STD-810 and MIL-STD-461).

HT1KWMP Outdoor IP65 Backup Power System

When to use:

  • When your application is exposed to harsh environmental and physical conditions such as:
    • Corrosive atmosphere (ships, hydrogen plants)
    • Heavy rain
    • Water splashes
    • Extreme dust
    • Extreme temperatures
    • High shock and vibration
    • Difficult access
  • Extreme dust
  • Extreme temperatures
  • Hight  shock and vibration
  • Difficult access

How to install:

  • Outdoor pole mounted

    • Telecom antenna
    • Security camera / speed control cameras
    • Intelligent traffic solutions
    • Offshore wind farms and oil rigs
  • Onboard wall/chassis mounted

    • Outside broadcasting
    • Transportation systems (trains, boats, etc.)
    • Military operations

Principle of Operation

Each module can supply up to 1000W on any AC, DC or combination of both AC and DC output ports. The three fully bidirectional ports (AC/AC/DC) built into each module can all function as input and output. This means you can use it to secure AC & DC loads and charge the batteries at the same time. The internal DC energy buffer dynamically distribute the power between AC and DC according the needs. No configuration is required.
