Line /Generator Battery Chargers
Isolated Switch-mode chargers used as on-board EV charger,
Solar back-up from a generator and industrial Battery charge.

               Equalization.
Charge Phase Indications: by LEDs.
Protections: Against over-current, over-heat and  reverse battery connection.
Alarm:   Beeper to attract attention upon faults.
Size & Weight::  10x6x3.5 inches,     4 lb

EVC203-48V is an economic back-up choice for 48V solar power system.

Sealed models of this chargers are customordered for boat and wet applications.
CHARGE ALGORITHMS:

The algorithm offered in our chargers is as follows (for Lead Acid):

RAMP PHASE: The charger starts by ramping from 0 Amp to its maximum current.
BULK PHASE: feeds  maximum current, to battery until voltage reaches ABSORB (2.45V per cell).
ABSORB PHASE: Keeps the battery voltage at ABSORB value. As battery is charged, current drops.
The charger turns oFF when charge current drops below 3A.
EQUALIZATION PHASE: this feature is periodically selected by a switch. It applies a higher voltage
(2.55V / cell) to the battery for 5 minutes.
CHARGE COMPETE PHASE:  It stops or optionally goes to FLOAT PHASE (lower constant voltage
phase).
EVC101:  500W Switch-mode charger:
- Compact Isolated charger ordered for 24 to 48V battery for small EV (Scooter, etc).
- It provides 500W charge ( 10A for 36V battery)
- It automatically provides Maximum Constant Current and Constant Voltage phases.
- Compact (8x4x2 inches and 2 lb)
- Low Cost
- Bulk and Absorb charge phases.
EVC207: 3KW Isolated Power-Factor-Corrected On-Board Charger
Ordered for 48V to 150V Battery from 115VAC, 208VAC or 230VAC

This compact Isolated Charger is POWER FACTOR CORRECTED (PFC):
It takes wide input voltage range (90 to 260VAC) and draws only
sinusoidal input current (so, your hydro meter registers useful energy).

TECHNICAL SPECIFICATIONS:
Input Voltage:     90 to 260VAC
Output Voltage:  up to equalization voltage of the ordered battery (190V for 144V battery).
Output Current:  3000W  divided by absorb voltage. For example, 20A for 96V battery.
Efficiency:  at least 90%
Isolation:  The line input and battery output are galvanically isolated.
Controls: Standard unit automatically performs a multi-stage charge.
Firmware upgrades: is factory provided for future battery chemistries.
Temperature Sensor: Internal  sensor measures ambient temp.
Charge Phase Indications: by 3 LEDs.
Protections: Against over-current, over-heating and  reverse battery connection.
Alarm:   Beeper to attract attention upon faults.
Size & Weight::  12x8x3.5 inches,     8 lb.
