Description
Voltage regulator-LHVR230/LHVR230H LHVR230/LHVR230H series circuit is a precision voltage positive stabilized power supply module especially designed for operations under high temperature and wide range temperature environment,Website:http://www.drillingpartss.com, this voltage regulator has the characteristics that output doesn’t change as the input voltage, load current and environment temperature. Without connection with the external filter capacitance, the output noise is less than 1mV, and can operate reliably for long term period under shell temperature of 230℃.?The devices can be widely used in oil well logging, programmable power supply and other harsh environments.Product characteristics: Output current: 1.5AInput voltage: 40VWorking temperature: -55℃～+250℃Storage temperature: -65℃～＋250℃Power: LHVR230/250-15W；LHVR230H/250H -30WParameters Test conditions Test temperature Typical values Parameters Input voltageVin1Vin2Vin1Vin2Input DC voltage while testing8V（Vo2+4）V（Vo1-4）V（Vo2+4）VThe minimum input DC voltage+7.5V（Vo2+2.5）V（Vo1-3）V（Vo2+3）VLoad current1AOutput voltage accuracy±1%Output noise≤1mVVoltage regulation rate（Vin=VT~30V）?±2%±0.5%Current load regulation rate±2%±1%Output voltage temperature shift(Tc=230℃)±120ppmProduct models:Parameters Test conditions Test temperature Typical values Parameters Input voltageVin1Vin2Vin1Vin2Input DC voltage while testing8V（Vo2+4）V（Vo1-4）V（Vo2+4）VThe minimum input DC voltage+7.5V（Vo2+2.5）V（Vo1-3）V（Vo2+3）VLoad current1AOutput voltage accuracy±1%Output noise≤1mVVoltage regulation rate（Vin=VT~30V）?±2%±0.5%Current load regulation rate±2%±1%Output voltage temperature shift(Tc=230℃)±120ppmDimensions and lead arrangement Note :All kinds of high temperature resistant positive voltage regulators with different output voltage can be customized according customers’ requirements.Purchase details: ?Payment Term:
