About This Instrument
The Vartech PPSA-100W-8005 S is a next-generation slim auto-ranging programmable DC power supply with 100 W output. Auto-ranging allows wider combined voltage and current coverage than a conventional fixed-range supply — within the 100 W envelope the voltage and current limits automatically trade off, maximising the usable output range. Features include RS232 & RS485 standard interface (SCPI and ModBus-RTU), remote sensing (compensates up to 2 V lead drop), external trigger, list mode (100 groups × 4 memories), data recording software, 4-digit displays, and comprehensive protections (OVP, OCP, OTP). Resolution is 10 mV / 1 mA.

- List mode — 100 groups × 4 memories
- External trigger via rear-panel 2-pin terminal
- Data recording software included
- OVP, OCP, OTP protections | Resolution: 10 mV / 1 mA
