Dear customer,

the voltage regulator is designed to supply a deﬁned, sta-

bilised voltage to your receivers and servos. lt is a com-

pact, lightweight device with an excellent performance,

and has been developed and manufactured in-house.

This unit enables you to use modern LiPo, LiIon, NiMh or

LiFe batteries as the power supply in your models.

The device is based on an IC which delivers a regulated

linear voltage of 5.3 or 5.9 Volt; these values are ﬁxed, and

cannot be altered.

A constant voltage substantially increases the effective

life of all the components of your RC system, but especi-

ally of the servos. The totally unvarying voltage provides a

substantial increase in the useful life of all components,

but especially of servos. Since the regulated voltage is

maintained at an absolutely constant level, all servos al-

ways operate with equal power and speed - regardless of

load.

Any servo feedback currents which may arise are reliably

eliminated by an electrolytic capacitor of generous capa-

city. Since the voltage regulator weighs just 12.5 gram-

mes it can be installed in any model without imposing a

signiﬁcant weight increase.

The regulator has proved particularly useful in small to

medium-sized ﬁxed-wing model aircraft and helicopters,

and for ignition systems. lt can also be used to reduce the

voltage to individual servos or other RC system compo-

nents.

The signal wire is looped through the regulator, enabling

the unit to be used to power individual servos at a reduced

voltage. This arrangement is primarily of interest where

the main RC system power supply is designed for HV ser-

vos (7.4 V), but where one or two servos are not approved

for use at the higher voltage. In this case the non-HV ser-

vos can be plugged into the voltage regulator and used

in the normal way. These are often tail rotor servos or

electronic components such as lighting units, valves etc.,

which must be operated at a lower voltage than the other

parts cf the receiving system. The unit can be connected

using a Uni, JR or Futaba connector. Caution! Connecting

the battery plug offset to one side will instantly ruin the

regulator.

The JR lead attached to the voltage regulator can be

plugged directly into the receiver socket.

If you wish to use a switch in the receiving system power

supply circuit, we recommend that you ﬁt it between the

voltage regulator and the battery.

lt is also feasible to use LiPo batteries with our PowerBox

12 switch backer (without integral voltage regulation) if

you connect one voltage regulator to the system for each

battery.

The regulator can supply 2 to 3 Ampere - according to bat-

tery type and cooling efﬁciency - which is adequate for mo-

dels ﬁtted with 6-8 standard servos or 4-5 digital servos.

Since any voltage regulating device generates waste heat

(varying according to current drain and input voltage), the

regulator should always be installed in an open position in

the modal, i.e. not enclosed.

The regulater is completely encapsulated using the mo-

dern „hot melt“ process; this renders it totally impervious

to vibration and moisture of all kinds.

GUARANTEE CONDITIONS

At PowerBox-Systems we insist on the highest possible

quality standards in the development and manufacture of

our products. They are guaranteed “Made in Germany”!

That is why we are able to grant a 36 month guarantee

on our voltage regulator from the initial date of purchase.

The guarantee covers proven material faults, which will be

corrected by us at no charge to you. As a precautionary

measure, we are obliged to point out that we reserve the

right to replace the unit if we deem the repair to be eco-

nomically unviable.

Repairs which our Service department carries out for you

do not extend the original guarantee period.

The guarantee does not cover damage caused by in-

correct usage, e.g. reverse polarity, excessive vibration,

excessive voltage, damp, fuel, and short-circuits. The

same applies to defects due to severe wear.

We accept no liability for transit damage or loss of your

shipment. If you wish to make a claim under guarantee,

please send the de-

vice to the following

address, together with

proof of purchase and

a description of the de-

fect:

LIABILITY EXCLUSION

We are not in a position to ensure that you observe our in-

structions regarding installation of the voltage regulator,

fulﬁl the recommended conditions when using the unit, or

maintain the entire radio control system competently.

For this reason we deny liability for loss, damage or costs

which arise due to the use or operation of the voltage re-

gulator, or which are connected with such use in any way.

Regardless of the legal arguments employed, our obliga-

tion to pay compensation is limited to the invoice total of

our products which were involved in the event, insofar as

this is deemed legally permissible.

We wish you every success using your new voltage re-

gulator.
