General Overview
The ProTech-4 battery charger will operate from 90 to 270 VAC, 45 to 440 Hz single
phase. The charger is designed specifically for the marine environment, with an
anodized aluminum case for effective heat dissipation and corrosion resistance.
The charger should be permanently mounted in your boat and wired directly to
your batteries. Three isolated positive outputs are incorporated to sense and
charge three separate heavy-duty batteries or battery banks as needed.
The ProTech-4 battery charger is reverse polarity protected and is equipped with
two cooling fans for optimum performance. The ProTech-4 battery charger’s fans
will not run at all times. The fan will turn on as needed for cooling.

No LEDs
The charger appears to have a series of LED lights on the outside in plan view. This is
not the case; the charger actually has a viewing hole on the battery connection side.
The LED’s will only light up when the unit has AC (120v or 240v) power.
GEL Cell charging mode
First, make sure that the charger is off and has no power. By removing the small cover
where the battery cables are located observe the black switch with two positions, position
1 is for Lead Acid batteries and AGM (Absorbed Glass Mat). Position 2 is for GEL cell
batteries. The Protech-4 is also equipped with an indicator light that illuminates yellow
for Lead Acid /AGM and green for the GEL cell setting.
External Fuse Box (for 30 Amp Units and Larger)
The fuse box outside the charger with a yellow cable attached is for negative DC (12 Volt)
reverse polarity protection, design to protect the charger from reverse polarity (reversing
negative and positive wires) this feature protects the charger from damage.
Note: When changing the configuration of your charger, make sure AC power is
disconnected.
Installation Guidelines
The charger should be securely fastened with stainless steel screws or through-
bolts with lock nuts. Vertical mounting on a bulkhead is preferred, but mounting
in any position that allows air to circulate with six inches of clearance space on
all sides is required. The ProTech-4 battery charger operates at ambient
temperatures up to 50 degrees C/140 degrees F.
The Protech-4 has a fuse block on the negative side (30 amp and larger) to protect
the charger from reverse polarity. 10, 15 and 20 amp chargers have a reverse
polarity fuse located inside the unit.
The 30 amp and larger chargers in the ProTech-4 family are equipped with an
AC input selector switch to change the Voltage from 120 Volt to 240 Volt. Smaller
chargers with less than 30 amp output do this automatically. (Voltage switch
shown below)
