1. Safety Precautions

• Before starting please carefully read entire User's Manual to ensure safe product use.

• High power electrical systems e.g. RC model's equipment pose dangers and it is the user's

responsibility to be familiar with these dangers and take any necessary action to ensure safe
use. Shorting a rechargeable battery can supply huge currents and have serious
consequences including explosions, causing fire, damage to equipment and personal injury.

• This product is designed to be safe to use when operated within the parameter limits it was

designed for. Typical applications are well within these limits, but it is the user's
responsibility to be familiar with the product specifications and ensure the unit is operated
within its limits.

• The current measured by the device may have a very large value. Poor connections may

cause large increase of temperature and risk of personal injury, fire and property damage.
The user must be familiar with the relevant methods, procedures and connection
components. It is suggested that any connectors and wires chosen for use be appropriately
sized and rated for the intended application and attached in the manner recommended by
their respective manufacturers.

• Before connecting a battery or power source it is necessary to verify polarity and there are

no exposed wires or connectors at risk for a short circuit.

2. Introduction

Energy Meter and Limiter KLW202 was designed for R/C boats with special needs such
as high current consumption, water resistance. During production we use potting process, a
complete electronic assembly is filled in a vacuum with a solid compound. The device maintains
high measurement accuracy even after sinking.

The device has a double function. Energy Meter shows in real time the amount of
energy consumed. Limiter after reach the programmed limit of energy reduce the throttle demand to
the ESC. The device allows to program four different energy limits. Switching between them is
done by short pressing the SET button. The ramp time, throttle minimum and limit time could be
programmed.

The KLW202 is a perfect solution for training and competitions. During training user
can set any value of energy limit and see how many energy consumed. During competitions limiter
is programmed and the SET button is sealed with a non-removable sticker, user can’t change
settings.

If the energy limits will be updated by NAVIGA, there is no need to return the device to
the manufacturer or to buy a programmer. The change can be made yourself from the menu by
holding down the SET button for a longer time.

Features:

● Current measurement up to 200 A.

● Minimal power loss by the use of silicone connecting cables with a cross section area of

10 AWG (5.3 mm2) and sensor resistor of 0.0001 Ω.

● High waterproof, IP67.

● No need a special programmer and additional switch button

● High accuracy.

● Clear LED display.

● Double function: energy meter and limiter.

● Fast changing a limit value, 4 values are stored in the memory

● High credibility, value of the programmed limit and other parameters could be shown on

display at any time.
