    2. Gamatronic three phase modular UPS for 480Vac In general, an Uninterruptible Power Supply (UPS) provides backup power for use when the utility ac electric power mains fail or drop to an unacceptable voltage level. A Gamatronic UPS does this and much more.

  • Page 19: System Structure

    2.1. System structure Gamatronic three phase modular UPS comes in various base models that have a maximum power capacity of 240kVA. The UPS includes from one to eight modular lightweight hot swappable ac power modules, each supplying 30 kVA/kW and 1 to 4 modular lightweight hot swappable dc/dc modules each supplying 60 kW.

  • Page 23: Dc Converter Module (60Kw)

    3.3. Dc converter module (60kW) The dc-dc converter module converts the ± 240V dc from the battery bank to ±420V dc required by the inverter. The dc-dc converter module is also responsible for charging of the battery bank The dc-dc converter module is the key to the UPS's small battery footprint. The UPS supports up to four identical internal dc converter modules all operating in parallel.
  • Page 24 The UPS supports the use of standard lead-acid batteries. If you plan to use lithium-ion batteries you must supply your own BMS (Battery Management System), and you must follow Gamatronic special instructions for lithium-ion battery setup. Setup instructions are available from support@gamatronic.com UPS for 480 Vac Grid, User Guide, doc.

  • Page 25: Overview Of Operating Modes

    4. Overview of Operating Modes The UPS functions to supply ac electrical power to your load. The UPS has five primary modes of operation: 1. Normal mode 2. Battery mode 3. Bypass mode 4. ECO mode 5. External Manual Bypass mode The following sections provide a short summary of the function and purpose of each mode.

    standby state. Meanwhile, the rectifier continues to charge the dc converter that charges the battery during ECO Mode. When the UPS in ECO Mode detects an irregularity in the bypass input, the UPS transfers the load to the Inverter and feeds the load conditioned power. The advantage of operating a UPS in ECO Mode is that, in effect, the UPS operates as a stand-by UPS.

    8.2.4.1.3.1. Factors that can delay the automatic battery test If the UPS’s ac input voltage is high, the battery test is postponed until the UPS’s input voltage  becomes lower. A “high” input voltage in this case means “greater than the battery test voltage divided by √2”.

    To calibrate battery current: 1. Operate the UPS without a load and with batteries disconnected. 2. Perform the Set dc current offset function (only if the measured current is not zero). 3. Connect the UPS to its batteries and to a load and operate the UPS in battery mode. Figure 70: Calibrate Current 4.

  • Page 99: Figure 78: Lvd Battery Protector

    Although the battery is disconnected from the load, there is still a small voltage drain on the battery from other sources. If this drain continues for a long period of time it can result in a deep discharge of the battery, which shortens battery life. To protect the battery from deep discharge, the LVD function (Low Voltage Disconnect) enables the user to define a time interval after which the battery disconnects completely from all drainage sources.

When enabled, the battery disconnect takes place after the time interval (in hours) specified in the LVD screen. Any one of the eight output dry contacts can be used to signal that the LVD countdown is in progress.
