The NPB series is highly reliable, safe, and features flexible functionality, boasting numerous features that make it one of the most comprehensive devices in its class. Key specifications include a wide power range (120-1700W), 12/24/48V and 72V outputs, high efficiency (93%), and a high power factor (>0.98). It charges Gel, AGM, and wet-cell batteries, as well as lithium iron manganese batteries. Charging is configurable in 2 or 3 stages, and it features automatic voltage detection for lithium batteries. Voltage and current are adjustable via a potentiometer (120W and 240W models), and for other models via the SBP-001 or by adjusting the maximum current in automatic voltage detection mode. Multiple protections are included (SCP, OLP, OVP, OTP, battery polarity reverse protection), along with an on/off switch, a fully charged battery alarm, and a charger OK indicator. CANBus protocol for monitoring and programming the output curve, etc.
These chargers are certified for industrial use (Audio and Video and Information Technology, and Residential) 62368-1 and 60335-1/2-29 and are ideal for electric motorcycles and bicycles, caravans, IAVs, mobile robots, Rumba, surveillance systems, portable tools, electric scooters, etc.
Having discussed all these features of the series, we want to introduce the new version of these chargers, the NPB-450-xxNPF series. This device allows you to configure the charger via an app and NFC without it needing to be powered on. This is a convenience for the user, as it eliminates the need to purchase an SPB-001 device and connect it to a PC. Now, this configuration can be done quickly and easily via a mobile phone (it can also be configured with the SBP-001 programmer).
A very important improvement is the ability to configure a reset of the charging curves. As you know, these chargers were primarily designed for a single charge at the end of the day. For example, an electric vehicle that we connected to the charger at the end of the day. The problem was that the device never returned to charging stage 1 unless the charger was turned off and on again. This was a problem for applications where we had a load connected simultaneously or for charging lithium batteries.
The NPB-450-xxNFC allows you to enable a function that, when it detects that the voltage has dropped to a certain value, forces the charging process to start from stage 1. As mentioned, this can be used to charge lithium batteries that should not be kept in float mode, or for UPS or backup applications where the battery has a connected load.
