Shortly after launching the 450W/750W ultra-wide range charger and power supply multi-purpose NPP-450/750 series, MEAN WELL is now releasing the higher power— NPP-1200 series. The most important feature of this product is battery charger and power supply 2-in-1, which allows the user to flexibly switch its operating mode (factory default is set to battery charger). In addition to running 3 stage charging curve for lead-acid batteries, the unit can also be switched to provide constant voltage power supply for normal load. Switching the operation mode is as simple as plugging and un-plugging a short circuit pin on the front panel.
NPP-1200's key features include ultra-wide output voltage, adjustable output voltage via VR on front panel (10.5~21V, 21~42V, 42~80V), adjust output current from 50~100%, built-in thermal controlled cooling fan to reduce noise, -30~+70°C operating temperature, built-in remote ON/OFF control, compliance to ITE IEC/EN/UL62368-1 and household appliances EN60335-1/-2-29 dual safety, multiple built-in intelligent protection functions, and 3 years warranty.
The new series is a safe, durable, and cost-effective dual-purpose power supply/charger, and it is suitable for charging systems used for RV, RV trailers, electric scooter, skateboard, AGV, AMR, service robots, medical cart, electric wheelchair, portable light tower, yacht, security equipment chargers, etc. as well as providing power to drive industrial control, information technology, communication, security control systems and more.
