Soneil 48v 3.5 Amp Constant Current World Smart Charger Son4808SRF
Product Description

Protection provided: Reverse Polarity, Short Circuit, Over-Voltage, Over Current and AC Surge. Soft Start and Stop; Starts and stops gradually. No sudden in-rush of current. This protects both the batteries and any other circuits connected to the charger.

Soneil’s Battery Charger transforms the 115/230 VAC into 48 VDC at about 100,000 Hz (3333 times faster than conventional charger), which requires a much smaller transformer and this results in a unit of smaller size, low weight and improved efficiency. The 4808SRF uses sophisticated electronic circuitry with microchips. All present day computers use switch-mode technology.

Stage 1: Deep Discharge Charging Pulse Mode
The Charger starts charging at 0.5V and give pulse current up to 5V. This has effect of removing loose sulphation formed during deep discharge state of the battery.

Stage 2: Constant Current Mode (CC)
The charger changes to constant current 3.0A. When the battery voltage reaches up to 57.6, the charging stage changes from (CC) Constant Current to CV (Constant Voltage) mode.

Stage 3: Constant Voltage Mode (CV)
The charger holds the battery at 57.2V and the current slowly reduces. When the current reaches 0.5 C (C= Battery Capacity), it is called the Switching Point. The Switching Point is one of the great features of this battery charger that it can adjust the current automatically according to the battery capacity. Other chargers without microprocessors are not capable of adjusting the current automatically.

Stage 4: Standby Voltage Mode
The charger maintains the battery voltage at 55.2V and current slowly reduces to zero. Charger can be left connected indefinitely without harming the battery.

Recharging:
If the battery voltage drops below to 55.2V, the charger changes from any mode to Constant Current mode and restart charging. The charging cycle will go through Stage 2 to Stage 4.

This charger typically ships without output connectors, allowing customer to adapt the charger to their specific needs.

Most Helpful Customer Reviews
   48v Soneil Charger
on Feb 12, 2012, Ownership: Use regularly, Knowledge Level: AC/DC is more than a band
(1 of 1 customers found this review helpful)

Pros: Easy to use, operates exactly how I had hoped it would. Maintains my 48v battery bank daily.

Cons: Does not operate well when running it off of an inverter. When using with an inverter, it charges the batteries but only in a trickle mode. When plugged into a wall outlet, all stages are operational.
