The BW5000-DA48 is an industrial inverter (converter) in a 2U 19-inch rack enclosure. This inverter can convert a DC voltage from 48V to 230V AC alternating voltage (pure sine wave), but it also has a mains input with built-in static transfer switch. Due to its fast switching time of less than 5ms, it can provide excellent service in a UPS and makes a separate transfer switch unnecessary. The inverter can also operate with DC voltage only.
48V pure sine wave inverter
The inverter supplies 230V AC with a pure sine wave, ensuring that really all equipment will work with it. The 4000W inverter has a wide input range of 40V – 60V DC.
The inverter has a continuous power of 4000W but it can supply a peak power of 6000W for up to 10 seconds. So you always have sufficient 230V AC voltage available.
Via the settings menu, you can choose whether the inverter primarily draws its voltage from the DC (battery) or AC (mains) input. When the inverter detects a problem with the primary input, it immediately switches to the other voltage source.
Inverter with Modbus and SNMP
As standard, the BW5000-DA48 can be read via RS232/RS485 serial port with the ModBus protocol. The version BW5000-DA48-SNMP is equipped with an Ethernet connection with the SNMP protocol. SNMP, which stands for Simple Network Management Protocol, is the standard protocol for monitoring remote devices via TCP/IP. The version BW5000-DA48-SNMP does not have an RS232 port, but it does have RS485 for Modbus, and the SNMP port mentioned earlier.
Protection
The DC input voltage of, for example, a battery is measured by the inverter. If this voltage becomes too low, the inverter will sound an alarm and switch back to the AC input to prevent the battery from being discharged too deeply.
Besides voltage protection, the inverter/inverter is short-circuit-proof and protected against overload and over-temperature.
On the front, the current status can be read via the 4 LEDs and the LCD screen. Previous alarms can be read back via the menu.
The inverter is also equipped with 5 potential-free alarm contacts for feedback.
Applications
These inverters are mainly used in combination with a battery pack and charger to bridge mains power failures. It is also possible to operate on battery voltage alone.
Some application areas are:
- Telecommunications
- Data centres
- Control room
- 230V AC mains supply in a boat or vehicle
- Autonomous power supply
- UPS systems
With an inductive application (electric motor, compressor, pump, etc), you have to take into account a higher starting current. In this case, we therefore strongly recommend buying an inverter that can deliver 3 to 5 times the normal power of the motor.
Wide range
DWE offers a wide range of DC/AC inverters. The inverters are available from 800W to 8000W. Output voltages of 110V AC or 120V AC with 60Hz are also possible. Ask about the possibilities.
