Description: Protection board for ldmos mosfet sspa linear amplifiers.Include swr pwr bridge/tandem match 1.5-54MHz.High current DC switch.Features:- SWR protection • Overload protection • Current limitation • Short circuit protection • Over voltage protection • Diagnostic feedback with load current sense • Operating voltage 24– 58 VDC • Operating current 44 A max • On-state resistance 7.2 mΩ To allow the switch to be disabled by an emergency signal, there are 3 protection triggers placed on board: • high VSWR 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. Fine threshold tuning from 150W up to 1500W. • DC current excess protector to disconnect the amplifier if current consumption is more than preset level. Fine threshold tuning from 15 up to 40A. Red LED shows which trigger is on. 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)BT50085B has a min switch-off time as low as 30 microseconds, so fast enough to protect the amplifier in case of emergency.-Reset button to recover if go protection.THANK YOUSV2RIFSV2RKF Shipping is with fedex worldwide.Customs duties and import charges are the buyer's responsibility and are not including in shipping cost or the item's price.
