ATS2.0 is designed with highly functional capabilities where the user can interface with most demanding applications. The module can control MCB and GCB contactors as well as compact circuit breakers direct from its ports, where two independent signals are required for switching the breaker on and off.

The module allows the user to start the generator for testing or periodical maintenance. While the generator is running, the load can be transferred between mains and generator bus-bars, using the switches on the front panel. If, during this phase, the mains voltage fails, the unit automatically switches to “Auto” mode and connects the load to Generator output.

During operation, mains or generator phase voltages or frequency can both be displayed on the front panel, hence avoiding extra AC voltmeters to be used on the panel. All voltage values are displayed in True RMS values with high reading accuracy.

All unit parameters can be adjusted from the device configuration menu and all program parameter values can be seen on the controller display. The units can also be programmed to control the engine cooldown function, hence allowing simple engine starter units to be used with small capacity generator sets.

KEY FEATURES

• 3 phase Mains voltage and 3 phase Generator voltage measurement
• Switching of MCB and GCB contactors manually with the front panel push buttons
• 3 digit LED display
• 5 configurable I/O ports
• Automatic, Test On-Load and Test Off-Load operation modes
• Full digital calibration of all analog measuring variables
• Plug type terminals on the rear panel
• TrueRMS voltage measurements on both bus-bars
• Load transfer function on Mains frequency monitoring
• Load transfer conditional on Mains phase status (Lock-on Mains bus-bar)
• Remote start and stop operation interface
• Engine cooldown timer for simple Generator controller interface

KEY BENEFITS

• Each phase can be programmed seperately which allows the user to set the system to start the Generator when 1, 2 or 3 phases are out
• Can control pulse type breaker modules directly from its output ports
• The 3 digit LED display is used for voltage readouts and parameter monitoring hence eliminates the need of additional AC voltmeters on the panel
• Engine cooldown function allows simple engine starter units to be used with small capacity Gen-Sets
• Small mechanical outline for minimal control applications
• Full LED indicators on front panel for bus-bar status condition indication
• Configurable I/O ports for customer specific applications

EBC 2420M is designed with “Switched Mode” technology. The control system is also designed in such a way that; battery is charged in three stages:

• Constant current mode (protecting battery cells)
• Constant voltage mode (reducing the charge current)
• Float charge (compensation of internal self-discharge)

Constant current mode makes sure that; when the battery is drained down below its rated capacity, the high charge current flow into the battery is limited in order to protect the cells and reduce damage to the plates. Charging characteristics are compliant to DIN41772/ DIN41773; power limited.

When the required battery terminal voltage is fully reached, the charger keeps supplying just enough current in order to compensate for the internal self-discharge (float charge). This ensures that the battery can maintain its high charge state and deliver its rated output current, when ever required.

The charger is also designed to operate with Constant Power output, where full output power can be delivered into the load up to 60° C ambient temperature. The output power is linearly de-rated down to zero at 70°C. This function ensures that the charger can deliver maximum available power to the load under any operating conditions without reducing charger reliability.

Typical Cell charging characteristics of the charger is shown in the table. The Cell is part of the battery and 24V batteries contain 12 cells. Factory setting of the charger allows each Cell to be charged to 2.30Vdc, which corresponds to 27.60Vdc terminal voltage. User can use an option up to 2.45Vdc per Cell, which corresponds to 29.40Vdc battery terminal voltage.

Each charging stage can be seen on the table. Initial cell charging is achieved with constant current mode, which limits the current such that it does not damage the cell plates. Normal charging time should be calculated as 10hr to 12hr. This requires typical charging current rating of 10% of the rated battery current capacity.

After the initial charging stage is completed, charge current starts to decrease as the cell voltage approaches 2.30Vdc. This takes approximately 60% of the charging period and is necessary to equalize each Cell voltage within the battery. During this period, the charger ensures stable constant voltage across the battery terminals.

After the charging is completed, the battery keeps draining current from the charger in order to compensate its internal resistive losses, called Self Discharging of the battery. This needs to be compensated in order to keep the battery charge at its highest condition.

If reverse polarity protection is required, user has to fit an external fuse in the charge circuit with the indicated rating in the table.

Charge failure alarm relay is built in and no need for an external relay use. The alarm output is a dry contact, potential free relay output with 3A/250Vac rating, which is energized in normal operation.

Boost charge can be initiated by pulling the “Boost Charge” input to ground with a relay contact. Boost will be in operation as long as the contact is closed.

The charger enclosure is made from Aluminum alloy metal sheet and the unit can only be fitted as rail mounting. Total weight is 1400gr.

Care should be taken in order to make sure that the perforations on the metal enclosure is not covered and free air ventilation is maintained within the panel. Otherwise, excess accumulated heat will degrade the overall efficiency of the charger unit.

  • Aluminum alloy case for robust handling and easy mounting
  • Both screw type or rail mount kit avaliable (Rail mount kit is an extra)
  • Overall efficiency > 82%
  • Boost charge function
  • Reverse power and reverse polarity protection with internal fuse,
  • Noise input filter
  • Solid State contact alarm output
  • Compatible with all types of Lead Acid and Nikel Cadmium (Ni-Cad application must be stated upon order) batteries
  • 3 stage battery charging

  Constant Current Mode – to protect the battery cells

  Constant Voltage Mode – to reduce the charge current

  Float Charge Mode – to compensate internal self-discharge

KEY BENEFITS

• SMPS technology increases the overall efficiency, hence reduces the excess heat dissipation in return, increasing the device life-time and reliability
• Elimination of fans and moving parts maximize the reliability
• The power de-rating function ensures the charger protects itself at high temperatures and does not fail
• Low output voltage ripple allows the unit to be used as a Power Supply if required (Must be stated while ordering)
• Three stage charging ensures best performance and reliability
• The noise input filter provides EMC reduction
• User operated Boost Charge function to replenish the battery charge storage capacity to high levels
• The alarm output can be connected to a Gen-set controller for monitoring
