Directivity of 22 dB from 26 dB 70 to 146 MHz. LCD SWR power meter indicator for LDMOS MOSFET tube amplifier 2400W max. The device is designed to display on the LCD alphanumeric display the values of the forward power and VSWR. For this purpose it should be connected to the directional coupler of any design, say Tandem-match. The forward voltage must be applied to the input port F, reflected to input port R. Power supply voltage is +7.5... Minimum voltage from directional coupler (SWR bridge) +2.55V. For proper operation the device requires calibration. Calibrate the Power Meter reading with trimpot FWR on reference instrument. Calibrate the readings SWR by REW trimpot on the reference meter connected in series to the antenna or using the load with known resistance , such as 100 ohms. In this case, the VSWR set to 2.0:1. Smart High Current DC Switch with protection triggers for power amplifiers. The application of this DC switch is to gate the power supply current to solid-state amplifier and safely disconnect it in case of emergency. Diagnostic feedback with load current sense.

Operating voltage 5 58 VDC. To allow the switch to be disabled by an emergency signal, 3 protection triggers are added to board. Protector to disconnect the amplifier from power supply if SWR rises higher than preset.

Level 2.0:1 (may be varied by user). Forward and reflected wave voltages from external directional. Coupler must be provided to determine the. VSWR independent of power level.

Output power excess protector to disconnect the amplifier if output power is more than preset level. Threshold tuning from 150 up to 1500W with one BTS660P and 150 up to 2500W with two BTS660P in. DC current excess protector to disconnect the amplifier if current consumption is more than preset level. Fine threshold tuning from 20 up to 40A with one BTS660P and 40 up to 80A with two BTS660P in. Red LED shows which trigger is on. Power off and then on to reset device. The onboard current sensor provides about +1VDC at 30 Amps for external current meter.

Meter impedance must be at least 10 KOhm. BTS660P has a min switch-off time as low as 30 microseconds, so fast enough to protect the amplifier in case of emergency.

Two BTS660P units may be installed on PCB to provide the current up to 2500 W amplifiers without additional heatsinks. 0-1500W 88-108MHz 7 pole Low pass filter module for FM transmitter. Loss: Max 0.15dB, Typ 0.1dB.
