DESCRIPTION
The HE1U-5012-BC-MU is a Heavy Duty AC to DC 750 Watt Power Supply, a low voltage disconnect, and a float charge
circuit in a 1U chassis. The HE1U-5012-BC-MU comes with power factor correction, and four layers of protection against overload, over
voltage, over temperature, and short circuit. This model also comes with a manual battery disconnect switch, internal power supply
ON/OFF remote control, and DC-OK. The HE1U-5012-BC-MU comes with a 3 year warranty.
The new internal Remote Monitoring and Control Unit (RMCU), provides the ability to remotely monitor the AC voltage, power
supply current and voltage, battery voltage and current, and internal temperature, as well as the ability to remotely control the ON/OFF
State of the power supply unit, all via the internet using any standard web browser. A mobile-friendly version of the status page is also
included.
Users that have access to the network can view the status of the power supply, control outputs, and the alarm conditions, as
well as download a .CSV file of logged states. Administrative users can access the setup screens and change the control settings by
logging into the RMCU via the browser. Alarm conditions are configurable, and can include over and under thresholds. Alarm
notifications can be configured by an administrator to send email and SNMP traps. Setups are saved in non-volatile RAM, and a battery
backed up real-time clock is provided to timestamp information logged to the internal SD card. Logging rate is user settable.
The HE1U-5012-BC-MU comes with the DuraComm three-year warranty.

INSTALLER NOTES
NOTE: DO NOT block any of the cooling vents on the sides and top and always allow adequate ventilation by not installing the unit
inside tightly closed spaces. Physical mounting position is not critical but the cooling vents must not be blocked.
NOTE: The outputs are NOT referenced to the chassis. The Modular System can be used either positive or negative ground.

HE1U-5012-BC-MU Wiring Layout
This system setup will provide continuous power to the load and maintain the battery bank with a float charge circuit while AC
power is on. There is a seamless transfer of the load to the battery when the AC power goes off. The LVD will disconnect the battery if
the voltage drops below 10.5 VDC. The battery reconnects once AC power is restored and voltage reaches 12.5 VDC.

REMOTE MONITORING AND CONTROL (HE1U-5012-BC-MU) SETUP
All setup requires an administrative user to log into the HE1U-5012-BC-MU in your power supply. Click the ‘Login’ button in the top
menu.
User Login
Enter the user name and password. Factory default username and password are as follows:
Admin Users have full control of the device.
Username: admin (cannot be changed)
Password: admin
Control users have limited control capability.
Username: control (cannot be changed)
Password: control
These two users are the only ones available in the HE1U-5012-BC-MU. “Control” users can access all screens except the User Setup
screen.
