Description: PROTECTION BOARD 2500WFeatures:• Overload protection• Current limitation• Short circuit protection• Over voltage protection• Diagnostic feedback with load current sense• Operating voltage 24 – 58 VDC• Operating current 80 A max• On-state resistance 7.2 mΩReset button to recover from protection. To allow the switch to be disabled by an emergency signal, there are 4 protection triggers placed on board:- High VSWR protector to disconnect the amplifier from power supply if SWR rises higher than presetlevel 2.0:1 (may be varied by user)-Forward and reflected wave voltages from dual internal directional coupler determine the VSWR independent of power level.- LPF error high SWR (may be varied by user).- Output power excess protector to disconnect the amplifier if output power is more than preset level. Finethreshold tuning from 150W up to 2500W.-DC current excess protector to disconnect the amplifier if current consumption is more than preset level.Fine threshold tuning from 15 up to 80A.Red LED shows which trigger is on. Press button to reset device.BT50085B has a min switch-off time as low as 30 microseconds, so fast enough to protect the amplifier in case of emergency.Board size: 120x47mm Dual Tandem match board Freq. 1.5-54MHzBoard provides output for protection board and for LCD pwr swr meter. First tandem match is connected between amplifier output and LPF to measure LPF swr/error and second tandem match is connected from LPF out to antenna and measure PWR and antenna SWR. Boards size: 100x80mm The on board current sensor provides +VDC for external current meter. Meter impedance must be at least 10 KOhm.(Divide the current through the BTS switch by 13000, then multiply by 3300 so you get the supply voltage by "ID".This information is in the datasheet on BTS50085-1TMB)THANK YOUSV2RIFSV2RKF Customs duties and import charges are the buyer's responsibility and are not including in shipping cost or the item's price.
