1～15KVA power inverter

1) Product introduction:

DLNB series 1～15KVA power inverters are designed for power plants, substations, power supply bureaus and other places to meet the requirements of high load rate loads, play the role of monitoring, carrier and relay protection, and are often used together with relevant power supply systems during operation.

2) Application field:

Thermal power plants, hydropower plants, wind power plants, nuclear power plants, garbage power plants, power distribution stations, substations, etc.

3) Performance characteristics:

01. MCU controller is used for control, switching, parallel algorithm processing and fault processing of the whole system, with good consistency and strong anti-interference ability.

02. In AC, the efficiency of power supply is up to 99%; The efficiency is up to 93% when the DC power supply is standby.

03. DC input and AC input/output are completely electrically isolated, without external isolation transformer, meeting the requirements of UPS power supply in integrated power supply design.

04. Ultra wide range of municipal power input, suitable for different environments.

05. The cooling fan adopts the combined speed regulation mode of temperature and output power. When the temperature is lower than 50 ℃ and the load is light, the fan runs at low speed with low noise; When the output load is heavy or the temperature is higher than 50 ℃, the fan runs linearly at speed and noise, and the fan has small size and long service life.

06. UPS has its own fault dry contact (normally open or normally closed), which meets the relevant requirements of the power industry.

07. Large screen LCD+LED display, RS232/RS485 communication interface, adapt to a variety of mainstream monitoring screen protocols.

08. Double inductance output, suitable for more load types, with output power factor greater than 0.8.
