The BU150U is a microprocessor controlled buffer unit rated at 20A and usable in 12V, 24V, 48V and 72V systems.
It monitors the voltage coming from a DC power supply for power interruptions.
In case of failure a capacitor bank is used keep the output regulated for at least 300ms at full load.
Benefits of the BU150U system,
- Charge much faster than batteries
- Can store much more energy than electrolytic capacitors
- Have a longer lifespan then batteries
For a lifespan comparison, consider that while capacitors have an unlimited number of charge cycles, lithium-ion batteries average between 500 and 10,000 cycles.
BU150U are used for graceful shutdown during blackouts, protection against power spike and protects voltage sensitive device from bad Electricity.
Provides 500W for 0.3sec
