80V / 5A Auto-Ranging Programmable DC Power Supply (100W)

About.

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.

• 0–80 V, 0–5 A max, 100 W - auto-ranging output
• Slim design - 55 × 140 × 315 mm, 1.8 kg
• RS232 & RS485 standard interface - SCPI and ModBus-RTU commands
• Remote sensing - up to 2 V lead-drop compensation
• 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
