FNIRSI Power & Performance

Clean power for the bench

The DPS-150 is a pocket-sized CNC-programmable supply that turns any USB-C PD charger into a precision bench source, while the IPS3608 is a conventional AC-DC digital control supply for permanent bench duty.

Battery health, measured

The HRM-10 measures true internal resistance — the number that tells you whether an 18650 or LiFePO4 cell is fresh or fading. For vehicles, the BTM-24 tests 12V/24V batteries up to 2000A CCA and checks cranking and charging systems in the driveway.

• Electronics projects: DPS-150 + HRM-10.
• Garage & 4WD: BTM-24.
