Isolated Hermetic Surface Mount Package 1.5 Amp, High Voltage, Positive Adjustable Voltage Regulator


Hermetic Isolated Surface Mount Package Adjustable Output Voltage Eliminates Stocking Fixed Voltages Built-In Thermal Overload Protection Short Circuit Current Limiting Product Is Available Hi-Rel Screened Electrically Similar To Industry Standard Type LM117HV


This three terminal positive regulator is supplied in a hermetically sealed metal surface mount package. All protective features are designed into the circuit, including thermal shutdown, current limiting and safe-area control. With heat sinking, they can deliver over 1.5 amp of output current. This unit features output voltages that can be trimmed using external resistors, from 1.2 volts to 57 volts.

VPM24-1040 : XFRMR 25VA MED GRADE CHASS MNT. Triad Magnetics introduces the VPM series of medical-grade toroidal isolation transformers offering both 4 KV of dielectric isolation and low-voltage step-down. The VPM series’ single-transformer solution leads to fewer parts and higher efficiency than using the typical space- and time-consuming solution of using.
