15W
MAX BOOSTER, with SWR protection
|
|
By PCS Electronics
- new massively improved model
This wideband no-tune FM
broadcast band amplifier unit was developed to supplement the PCI MAX
line of fm transmitters, but will work great with any LPFM (low power
fm transmitter) on the market. It takes the signal and amplifies it to
the full power of 5W / 15W. It can also be used to power other smaller
transmitters, up to about 1W of their output power (with engaged attenuator).
It does not require tuning as it a wideband no-tune design. It also features
a built-in SWR foldback protection that shuts the power off as soon as
the SWR reaches critical levels. Unit works from a stabilised DC power
supply (12-15V at 4A).
What's
cool:
- Power is now linearly adjustable from the outside via the provided potentiometer
- Truly
wideband
-
SWR protection circuit
- It CAN be used with PCI MAX cards directly
IMPORTANT NOTE: If you use a 12V fan for cooling,
these units typically push 15 - 20W of power.
Here
is the manual for the new 5W/15W booster.

Features:
RF Input Power: 25-250mW (selectable
hi/lo via jumper)
RF Output Power: 5W (5W model) or 15-20W (15W model 20W max.)

Adjustable from 0 to max via potentiometer.
RF output power can be hard-limited internally to 1W max for 5W model
only.

40W FM amplifier
An ultra compact FM amplifier
employing the latest RF techniques for an ultra-stable high effeciency
design. This unit can be supplied with a universal input switched mode
power supply. This can be used on any mains voltage system in the world.
A built in heatsink and fan assembly provides more than adequate cooling
to the unit ensuring 24 hour operation. On board harmonic filtering provides
that needed reassurance that your signal is where it should be. The 4
Watt input version works perfectly with our MAX PRO I transmitters (exciter
needs to be run at 12V DC to reduce power to 4W). Supplied with
a cooling fan for worry free 24 hour operation.
It
is NOT possible to use this unit with PCI MAX 2004!

Features:
Power Output 40W
Power Input 4w (can be modified to 1W)
Harmonic Output -60dBc
Spurious Output -80dBc
Input voltage (PA module) 24 volt nominal
Input voltage (Power supply) 90-270 VAC
Dimensions, PA 125mm x 55mm x 90mm
