PG1275 Surge/Spike Generator MIL-STD-1275D

 

Overview

The Montena PG1275 is a dedicated surge and spike generator for verifying the susceptibility of 28 Vdc military vehicle power systems in accordance with MIL-STD-1275D. It supports both imported and exported spikes and surges on the 28 Vdc bus, providing a compact, fully controllable source for development and compliance testing of military electronics. 

 

With a built-in 5 µH / 400 A inductor and robust 400 A output connectors, the PG1275 is engineered for high-current DC circuits typical of military platforms. PC control via RS232 or USB allows test automation and repeatability in modern EMC test labs.

 

Key Features & Benefits

  • Purpose-built for MIL-STD-1275D transient testing on 28 Vdc power buses 

  • Generates both imported and exported spikes and imported and exported surges

  • Supports surge voltages up to 125 V and spike charging voltages up to ±500 V 

  • Internal 5 µH, 400 A inductor for realistic line impedance and high-current operation 

  • High-current ITT IP67 400 A output connectors for reliable connection to DUT and power network 

  • Full remote control via RS232 and USB for integration into automated test systems

  • Wide-range AC input (90–264 Vac, 50–60 Hz) for flexible installation in global labs
