Overview

NPB-1700-24 is the model of this series: typical efficiency 93%.

NPB-1700 is a miniaturized, versatile, and ultra-wide voltage intelligent charger. It utilizes a fully digital control design with automatic battery voltage detection technology, with five key features including intelligent, versatile, user friendly, safe, and compact. The series have four models with output voltage ranges of 10.5~21V, 21~42V and 42~80V respectively. The charging voltage range of each model is wide enough to cover a variety of different battery voltages and battery chemistries, and there is a built-in intelligent voltage detection charging mode (Note this mode is set to OFF by factory default and is suitable for lithium batteries with BMS only). The NPB-1700 can pair with MEAN WELL's SBP-001 programmer for digital configuration, such as adjust charging voltage/current, and set charging cycle time to protect battery lifetime. Through the user-friendly DIP S.W. on front panel, user may also directly adjust the 2/3 stage charging, current (50~100%), and select between the 4 types of preset charging curves. In addition, a CANBus communication protocol is built in to meet professional applications, which allows remote controlling and monitoring for the status of the charger. In terms of safety, it has intelligent detection for proper battery voltage and connection as well as protection from reverse polarity. It passes ITE IEC/EN/UL62368-1 and household appliance EN60335-1/-2-29 dual safety and 3-year warranty to guarantee reliable operation. The NPB-1700 is truly an intelligent, safe, and reliable universal charger with outstanding cost performance.

FAQ

Can I use the Mean Well NPB-1700-24 to charge a 24V battery bank in industrial automation equipment?

Yes. This charger is built for 24V battery systems and provides a 28.8V default boost charge voltage with up to 50A constant charging current, and 1680W power for higher-capacity charging. It is suitable for both lead-acid and Li-ion battery chemistries.

Is the NPB-1700-24 suitable for large backup battery systems in IT or embedded equipment?

It can fit 24V backup battery systems where the charging profile matches lead-acid or Li-ion batteries and the AC source is within 90-264VAC. With a 28.8V boost charge voltage, 50A current and a recommended battery capacity of 200-640Ah, it is intended for higher-power battery charging.

Can this charger be used for high-current 24V battery charging in industrial vehicles or mobile equipment?

Yes, if the system uses a 24V lead-acid or Li-ion battery pack and needs a charger rated at 28.8V and 50A. The 1680W output and 200-640Ah recommended battery capacity suit high-current 24V charging.

Can the NPB-1700-24 work in facilities with different AC mains conditions?

Yes. Its 90-264VAC (250-370VDC) input range supports operation across a wide range of AC supply conditions, which is useful for industrial and commercial sites with different mains standards. The charger delivers a 28.8V default boost charge voltage with up to 50A charging current.

Is the NPB-1700-24 suitable for outdoor or harsh-temperature locations?

The specified operating temperature range is -30°C to +70°C (refer to the derating curve), so it is rated for very cold and hot environments within that range. The provided specs do not list an IP rating, so exposed outdoor use should not be assumed from this data alone.
