Overview

RM ITALY BLA600 Solid State Amplifiers

RM ITALY BLA600 Solid State Amplifiers are wideband, compact, automatic linear amplifiers for 160 through 6 meters; 1.8 to 54 MHz. Low input drive requirements (20 to 25W on 80-10 meters, 30-40W for 500W on 160m and 6m) make these amplifiers THE perfect transceiver companion!

RM ITALY BLA600 amplifiers are fully automatic 500W solid-state linear amplifiers suitable for seamless integration with all modern transceivers. They utilize the rugged NXP / Freescale MRF6VP5600H 50V power MOSFET for high power and high reliability.

These amplifiers are capable of all modern modulation modes. BLA600 amplifiers are fully automatic, featuring instant RF frequency-reading for band changes and fast, reliable and silent PIN diode TX-RX switching, making them ideal for CW QSK operation (separately purchased transceiver to amplifier PTT keying cable is required.)

BLA600 amps have three (3) antenna outputs that are easily configurable on a per-band basis as per the user's requirements. Their RF deck is supplied by a heavy-duty linear power supply, with 240 volt AC input* (115-120 or 230 VAC capable) and utilizes an efficient active bridge rectifier with very high-grade filter capacitors to provide the PA devices with a very low noise and robust 50V DC.

The amplifier's RF deck has a large heat spreader and copper heat sink which provides a very efficient cooling system. There are separate fans for the RF deck and LPF board / power supply for high duty cycle operation. Internally, all modules are mounted in a very robust and well-screened enclosure.

BLA600 amplifiers feature Dual MCU control and an extensive array of protection circuits that look after the amplifier with rapid reaction time. VSWR, I/P Power, I/P Frequency, Three Temperature sensors; Transistor / Heat sink and PSU, Drain voltage / Drain current and HV PIN supply are all continuously monitored.

**Requires a user supplied NEMA 6-15P to IEC 320-C13 Cord. (Internally resettable for 230 or 120 VAC input on jumper board under rear access panel secured with T10 torx screws)
* AC Input Fuse: 5 x 20mm F LBC 250V; Fast Blow, 240 VAC 5A (included); or 230 VAC 6A (optional) or 115-120 VAC 10A (optional, with NEMA 5-15P to IEC 320-C13 15A Cord.)

WARNING: Amplifier is set from the factory for 240VAC operation.
Do not use a low amperage PC power supply AC cord. An IEC C-13 14AWG 15A cord is required with NEMA 6-15P for 240VAC or NEMA 5-15P for 120VAC after internal jumpers and fuse have been changed.

If your HF transceiver can be set for 20 to 40 watts output, then you will be sending 500 watts to the antenna on ALL bands 160 through 6 meters using this amplifier. The real beauty is that it all happens fully automatically! There is no tuning and no band switching! Give your signal a nice boost.
