NPB-450-12

Mean Well battery charger series NPB-450

External battery chargers with 450W, a remote ON/OFF control, a built-in CANBus interface and a digital/manual setting of the charging stages (2/3). These devices are suitable for Li-ion as well as lead-acid batteries and are protected against overvoltage, voltage reversal, overtemperature as well as short circuit. They have a built-in DC fan, are configurable over an NFC interface (NPB-450-_NFC) and comply with EN62368-1, EN60335-1/2-29, EN55032 class B, EN61000-3-2 class A as well as EN61000-3-3. We offer the following types of this Mean Well series: NPB-450-12, NPB-450-24, NPB-450-48 and NPB-450-72.
