User Manual

The 2kW 48V 35A Portable Programmable Battery Charger is a high-performance charging solution designed for 48V battery systems. With a robust 2000W output and 35A current capacity, it delivers fast and efficient charging for lithium-ion, lead-acid, and other battery types. Its programmable features allow customizable charge profiles, including voltage/current adjustments and multi-stage charging. Compact and lightweight, it's ideal for EVs, solar storage, and industrial applications. Built with advanced protection (overvoltage, short-circuit, overheating) and an intuitive interface, this charger ensures reliability and user-friendly operation in diverse environments.

1. High-Efficiency Charging with 94% Conversion Rate
The 2kW 48V 35A portable programmable battery charger delivers industry-leading efficiency with a 94% power conversion rate. Utilizing advanced synchronous rectification and zero-voltage switching (ZVS) technology, it minimizes energy loss during operation. The charger maintains an input voltage range of 90-264VAC (47-63Hz) while outputting a precise 48VDC (±0.5% regulation). This efficiency translates to reduced heat generation, with thermal dissipation kept below 65°C at full load, ensuring prolonged component lifespan.

2. Multi-Stage Programmable Charging Profiles
Equipped with 8 user-defined charging algorithms, this charger supports CC/CV/float/trickle modes with 0.1% current resolution (35A ±50mA). The microprocessor-controlled system allows voltage adjustments from 36-60VDC in 10mV increments. Charge termination parameters include ΔV detection (±10mV sensitivity), -dV/dt (0.5-5mV/cell/min), and temperature cutoff (NTC 10kΩ ±1%). Users can store up to 15 preset configurations for different battery chemistries (Li-ion, LiFePO4, SLA, etc.).

3. Ruggedized IP54 Enclosure with Active Cooling
The charger features a military-grade aluminum alloy housing (EN AW-6061 T6) with IP54 ingress protection. The forced-air cooling system employs dual ball-bearing fans (12V/0.4A, 45CFM) with PWM speed control (800-4500 RPM ±5%). Vibration resistance meets MIL-STD-810G Method 514.6 (5-500Hz, 5Grms) while operating in -20°C to +50°C environments. The compact dimensions (220×130×60mm) and lightweight design (2.8kg) enhance portability.

4. Advanced Protection Circuitry
Comprehensive safeguards include:
- Input: Overvoltage category III (300VAC), 20A slow-blow fuse
- Output: Reverse polarity (60V/100A MOSFET), short-circuit (response<100μs)
- Battery: Overcharge (±0.25% voltage threshold), temperature derating (2%/°C above 45°C)
- System: Redundant overtemperature shutdown (85°C ±3°C dual sensors)

5. Smart Communication Interfaces
The charger supports CAN 2.0B (1Mbps), RS-485 (Modbus RTU), and Bluetooth 5.0 (BLE) for real-time monitoring. The 2.4" TFT LCD (320×240 RGB) displays 12 simultaneous parameters including:
- Voltage: 0-60V ±0.05% FS
- Current: 0-35A ±0.1% FS
- Energy: 0-9999Wh ±0.5%
- Internal resistance: 0-999mΩ ±1%
Data logging stores 500 charge cycles with 1-second resolution.

6. Universal Power Compatibility
The auto-ranging PFC front-end accepts 90-264VAC (47-440Hz) or 120-370VDC inputs, making it suitable for global applications. The charger meets EN 61000-3-2 Class A harmonics and achieves<0.99 power="" factor="" correction.="" emergency="" operation="" is="" possible="" via="" 12v="">
