WHAT IS
VOLTAGE SAG?
According to IEEE standard 1159-1995, a voltage sag is defined as a decrease in rms voltage down to 90% to 10% of nominal voltage for a time greater than 0.5 cycles of the power frequency but less than or equal to one minute.
Characteristic of voltage sags High frequency of occurrence The time of sag is unpredictable Short duration and deep depth
WORKING PRINCIPLE
DPS-ACTIVE is installed between the load and power supply, in the event of an outage, voltage drops or swells, DPS-ACTIVE will transfer the load to the backup energy storage system, powered by the super capacitors to ensure the sensitive loads are well protected.

DPS-ACTIVE provides fast accurate protection against sags and swells as well as continuous voltage regulation.
Even when the voltage drops to zero, the DPS-ACTIVE can still support the loads of 100% rated voltage, 2ms typical fast response.
APPROACHING THE
LIMIT OF ENERGY CONSERVATION LAW
99% HIGH EFFICIENCY
DPS-ACTIVE is an OFF-Line unit specifically designed to correct voltage sag and voltage swell. The inverters are usually in the standby state, only when the voltage exceeds the normal range, the inverter will start to work, which greatly saves energy consumption.
