TW7000 SERIES HF TRANSCEIVER section 4

DTX75000

The DTX75000 5kW transmitter/transceiver contains a fully solid-state amplifier and offers the efficiency of

class AB operation with the linearity of a class A design. It incorporates a sophisticated microprocessor-based

controller and is composed of four separate 1250 watt sub-units that are combined to obtain the total 5kW power

output. Includes the TW7000TX transmitter or TW7000 transceiver, 5kW amplifier, amplifier interface circuitry,

transmit controller, RF combiner, power supply, equipment rack, and connecting cables. The complete system is

integrated into a single 19-inch rack with internal forced-air cooling. It requires 360 or 408 VAC, 3-phase, 5-wire

power. Contact your Datron Sales Representative for more details.

2. Power Supplies and Adapters

Ac to dc power supplies are available to power TW7000 equipment used in a fixed station configuration.

Power cables must be ordered separately. Datron also offers a line of power switches is for use in battery backup

systems.

a. PF3000-110

b. PF3000-220

c. TWPSC

d. RAT1000P-110

e. RAT1000P-220

PF3000-110

Continuous duty, 12 Vdc, power supply designed to power the TW7000. Switch selectable for either 90-132

VAC or 180-264 VAC. Includes AC power cable with 110 VAC NEMA 5-15P plug and C991829 DC power

cable. For rack-mounted systems order the PF3000RM rack mount.

PF3000-220

Same as PF3000-110 except with 220 VAC NEMA 6-15P plug on power cord. For rack-mounted systems order

the PF3000RM rack mount.

TWPSC

Low current power supply adapter for transceiver. Provides automatic switching to backup DC power source if

power supply or AC mains fail. It’s a low current switch that provides backup for just the exciter (TW7000 @

125W PEP); if system is used with an associated RF Power Amplifier, the amplifier is placed in bypass mode.

Oder backup DC power source and cables separately.

RAT1000P-110

External 28 Vdc power supply for the RAT1000C antenna tuner. For 110 VAC systems. Used in 500W, 110

VAC, high power systems whenever a 12 Vdc radio is used or when the radio-to-tuner control cable run exceeds

50 feet if used with a 28 Vdc radio. Order C991933 (control + power cable between the radio and the

RAT1000P-110) and C991552 (control + power cable between the RAT1000P-110 and the RAT1000C)

separately. Specify C991552 length.
