Caution
The DZB7 is designed for use
with external, regulated,
. It
is the external power supply voltage value that sets the track voltage. The
recommended default setting is 15 Volts or lower. Higher voltages can damage
decoders. If you intend to operate at a higher voltage, you must first contact your
decoder vendor and ask them for the maximum voltage the decoder can withstand and
use that as the absolute maximum voltage setting for the external power supply.
ONLY
DC power supplies
Caution
Never apply AC voltage to the DZB7
power input jack. Doing so will damage
the DZB7 which will not be covered by
the warranty.
Caution
Short circuit and overload protection of
the DZB7 requires proper wiring
techniques and suitable wire. Be sure
and use the recommended wire size.
Warning
The DZB7 is not a toy and is not designed to be operated by children. It is a high
current device, capable of supplying up to 30 Amps of surge current and 7 Amps
continuously at voltages as high as 24 Volts. Read and follow all directions and
installation instructions. Do not expose to moisture; do not use outdoors. Never
block the rear vent holes. CVP Products shall not be responsible for any claim or
loss of any nature arising directly or consequentially from the use of this unit.

Maximum Output Power Limitations
Do not share a power supply among multiple boosters.
Each zone can supply up to 7 Amps of output current. However, the zones can not
simultaneously provide this amount of current because the DC power supply is limited to
8 Amps when set for 15 volts. Thus, if one zone is continuously supply about 5 Amps, the
other zone can not supply more than about 3 Amps. Exceeding this value will cause the
external power supply to shutdown.
For best operation, design your layout such that any one zone requires no more than about
4Amps maximum at any one time. This can be accomplished by considering how many
trains can be operating at one time within the zone. If the total current required by all the
trains exceeds about 4 or 5 amps, consider adding another booster. Using this strategy
insures that there is plenty of extra power to start trains, even if the zone is loaded down
with 4Amps.
At any point in time, either zone can supply up to 7Amps - they just cant do it at the same
time. If this is a requirement, you will need to add some additional boosters.
This is not allowed and can
cause problems between ZoneMaster Boosters.
Application Tips and Techniques
Do not attach any external devices to the output of the ZoneMaster Booster.
Do not connect any cables with power applied.
Do not use the ZoneMaster with the Analog Channel 0 feature
Disable the analog conversion feature of your decoders.
Use heavy duty wiring.
Test your wiring and trackwork.
Zone-Ahas a variable trip current control and can be used at any time.
For best
performance and maximum safety, dont use any external devices such as shields or
circuit breakers between the Booster and the layout. They can cause unpredictable results
and could damage the Booster. If you think you need such devices, consider selecting one
of our other ZoneMaster Booster that provide the same capability at a much lower price.
Conventional block detectors, used for signaling, are OK for the ZoneMaster Boosters.
Always make connections to the
Booster with power turned off. Under unusual conditions, connecting the modular cable
with the power turned on could result in unexpected locomotive operation.
. Some system allow a
locomotive without a decoder to operate. This feature is not supported by the ZoneMaster.
Consult your decoder manual
and set CV29 to digital only.
Because the ZoneMaster has a huge power capacity, your layout
needs to be wired properly. Using wire that is too small, or depending only on rail joiners
to connect lengths of track will result in the automatic short circuit protection not
working.
Go to the end of your bus wiring and place a metal
object or coin across the rails. If your wiring is OK, the short circuit beeper will sound
immediately. If it doesnt sound, you will need to beef up your wiring.
Although this
is normally used to set the auto-reverse sensitivity, it can be used when the auto-reverse is
turned off.

This is a universal supply suitable for all primary voltages found
throughout the world. The supplied plug fits most European wall outlets. However, feel
free to remove the plug and attach one that fits your wall sockets.
Before using the power supply, select
the desired output voltage using the slide switch. Once
selected, remove the appropriate voltage selector cap and snap
it in place. This is not mandatory but prevents accidental
changing of the output voltage.
Use the 15 Volt setting for
HO and O railroads. For LGB, use 18V. Always use the lowest
possible setting since the higher the voltage, the lower the
available current.
The maximum power output is 120 Watts. To determine
the maximum available current, divide the power rating (120W) by the selected output
voltage. For example, with the 15V setting, up to 8Amps can be supplied. However, your
specific booster will have its own maximum rating which may be less than the maximum
available from the power supply.
Under maximum continuous load, the power supply will
become hot. Keep the unit free of anything that will obstruct air flow around the unit. Do
not embed the power supply inside a sealed container. It must have airflow to achieve
maximum power.
The power supply is protected against overloading, short circuits and
overheating. The output will shut down should any of these faults occur and automatically
reset when the fault is cleared.
There is a small green LED on the front of the unit. WhenAC power is
applied, it will turn on.
DC Power Cord and Plug: The heavy duty plug fits directly into the ZoneMasters DC
input jack. Since the cord and plug can exert a large amount of up/down and sideways
force on the jack, support the cord to keep to a minimum and forces on the jack.
Connecting Power Supply To ZoneMaster:
Support the cord
This
is the easy part. Simply insert the plug and push it in

to minimize the
forces placed on the
