OPERATING INSTRUCTIONS

The DIGI-PEAK and DIGI-PEAK PLUS chargers are constant-current chargers designed to

charge 4 to 8 cell nickel-cadmium battery packs from a 10 to 18 volt DC power source.

The DIGI-PEAK chargers feature 10-bit Digital Peak-Detection Circuitry™ with automatic

shut-off. Three different charging modes allow you to fine-tune the charging. PULSE Mode

with 0 to 10 amps, LINEAR Mode with 0 to 5.0 amps, and TRICKLE Mode with 0 to 300

milliamps linear trickle charge. A built-in LCD meter on the DIGI-PEAK PLUS, and output

jacks for an external voltmeter on the DIGI-PEAK, let you monitor battery pack voltage.

DIGI-PEAK chargers are equipped with Solid State RVP™, thermal overload protection, and

heat sink temperature sensing auto-fan circuitry to control the optional cooling fan Kit #5635.

INTRODUCING THE DIGI-PEAK

Refer to the back page for more information.

STEP 1 CONNECT INPUT

• Connect the input alligator clips on the back of

the charger to a 10 to 18 volt DC power source.

DIGI-PEAK SET-UP

POWER SUPPLY REQUIREMENTS

As a general rule, the voltage of the input power source should be 1.5 volts DC above the

peak-voltage of the battery pack you are charging.

Example: (8 cell transmitter pack peak-voltage* = 13.5 volts) + (1.5 volts) = 15 volts DC

*Older battery packs will peak at higher voltages–Do not exceed 18 volts DC input voltage

ACCEPTABLE POWER SUPPLIES UNACCEPTABLE POWER SUPPLIES

Car Battery 12 volts DC Automotive Battery Charger

Power Supply 10 to 18 volts DC

SELECTING CHARGE MODE & RATE

IMPORTANT PRECAUTIONS

The following precautions will help to prevent possible damage to the charger, battery pack,

and the input power source.

• Charge only nickel-cadmium rechargeable battery packs. Nickel-cadmium batteries can

become damaged if the charging current used is too high. Maximum charging rates can

be obtained from the battery manufacturer. Do not trickle charge at a rate higher than

20% of the cell's rated mAh capacity for longer than two hours.

• Never allow water, moisture, or other foreign materials to enter the charger.

• Automobile battery chargers should not be used to power the charger. False peaks can

occur, and excessive voltage spikes can damage the charger.

• Do not charge battery packs with less than 4 or more than 8 cells connected in series.

• The heat sink on the back of the charger can get extremely hot during charging. Do not

obstruct or cover the heat sink or cooling fan (if equipped), as this will cause it to over-

heat and shut down. When charging 4-cell packs, the DIGI-PEAK's heat sink will get very

hot. If the heat sink gets too hot, the charger will go into thermal shutdown mode.

• To help cool the heat sink, use the optional Novak Cooling Fan Kit #5635. The charger's

Auto-Fan circuitry only runs the cooling fan when needed.

(Fan cycling on and off is normal)

• Never use an input power source which exceeds 18 volts DC to power the charger.

• Avoid open flames and sparks which may ignite battery gases. Always disconnect the zip

cord from the charger before connecting or disconnecting the alligator clips to a lead-

acid battery. Using a lead-acid battery as a power source generates hydrogen gas and

should only be used in a well ventilated area, as gases built up may ignite if sparks occur.

PLEASE FOLLOW ALL INSTRUCTIONS CAREFULLY

NOVAK!

The DIGI-PEAK chargers have three adjustable charge modes (LINEAR, PULSE, and TRICKLE)

for charging nickel-cadmium rechargeable battery packs. The following table lists typical

charging rates and recommended charging modes for popular cells used in the remote

control industry. While higher charging rates will peak your cells sooner, use of excessive

charging rates (above those listed below) may damage your batteries.

STEP 3 SELECT THE CHARGING MODE

Determine the proper charging mode from table above. Slide the LINEAR / PULSE

mode select switch to either LINEAR or PULSE. Refer to illustration in Step 4

The charger runs hotter in the more common LINEAR charging mode and may require the

optional Novak Cooling Fan Kit #5635 if overheating occurs. The PULSE mode will allow

higher charging rates and cooler operating temperature, which can be used if the charger

overheats in the LINEAR mode. Please note that charging rates higher than 5 amps may

decrease the number of useful cycles in the life of the battery pack.

TRICKLE CHARGING

Trickle charging is only available in the LINEAR mode and can be used to slow charge the

battery or equalize the cells in the battery pack. When the battery pack is connected and

the charger is in the LINEAR mode, it will automatically begin trickle charging until the

START button is pressed. When the battery pack peaks in the LINEAR mode, the charger

will again automatically trickle charge the pack. If the TRICKLE dial is set to zero, no trickle

charging will take place either before or after the charge cycle.

BATTERY PACK TYPE CHARGING RATE CHARGING MODE

SCRC cells 3.0 to 6.0 amps LINEAR

SCE, P-170, and P-180 cells 2.0 to 3.5 amps LINEAR

SCR cells (except Panasonic) 3.0 to 6.0 amps LINEAR or PULSE

Receiver Battery Pack (50 mAh) 0.5 amp LINEAR (Only)

Transmitter Battery Pack (AA) 0.5 to 1.5 amps LINEAR

TRICKLE CHARGE CHARGING RATE CHARGING MODE

SCRC, SCE, P-170, and P-180 cells 170 milliamps LINEAR (Only)

SCR cells 140 milliamps LINEAR (Only)

STEP 4 ADJUST THE CHARGING RATE

Determine the proper charging rate from table above.

Rotate the current adjustment dial that corresponds to

the charging mode used. Refer to illustration below

Use the enclosed screwdriver

or a small flat blade screwdriver

to make this adjustment.

Current dials are ±10% accurate

CAUTION: Do not connect

to AC power side.

STEP 2 CONNECT OUTPUT

• Connect the output alligator clips on

the front of the charger to a 4 to 8 cell

nickel-cadmium battery pack.
