The integrated, lightweight switching power supply enables operation with input voltages from 100 to 240 V AC and keeps the total weight of the device at a manageable 13 kg.<br \/>\nThe minimum power required for control is just 1 watt; full output power is achieved with an input power of 35 watts.<br \/>\nA large heat sink integrated into the housing, which is supported by 2 large (but quiet) fans, ensures optimum heat dissipation.<br \/>\nEasy-to-read LED bar displays on the front of the device provide information about the relative transmission power and the standing wave ratio (SWR) at all times during operation. A switchable receive amplifier enables effective amplification of weaker signals.<br \/>\nThe PL\/SO239 connections for transceiver and antenna, earth terminal, RCA socket for PTT control and the power supply connection are located on the rear.<\/p>\n<p><strong>The power amplifier offers the following protective functions:<\/strong><\/p>\n<ul>\n<li>Protection against excessive input power<\/li>\n<li>Protection against excessive SWR<\/li>\n<li>Protection against overtemperature<\/li>\n<li>Protection against unwanted out-of-band transmission<\/li>\n<li>Remote Control capabilities No<\/li>\n<li>Brand RM Italy<\/li>\n<li>Weight 13 kg<\/li>\n<li>Max.
