Tabletop power supply R&S®NGE100B

DCregulatedconstant-current

Overview
The R&S®NGE100B DC power supply series includes 2‑channel (R&S®NGE102B) and 3‑channel (R&S®NGE103B) laboratory DC supplies designed for low ripple, precise measurement and flexible channel configuration. Intended for R&D, education, production testing and maintenance, the series supports USB control as standard and offers optional LAN, WLAN and digital I/O.

Typical applications

• Research & development and product validation
• University and vocational training labs
• Manufacturing functional and burn‑in tests
• Maintenance, repair and service benches

Key facts

• Models: R&S®NGE102B (2 channels), R&S®NGE103B (3 channels)
• Max. total output power: 66 W (NGE102B) / 100 W (NGE103B)
• Max. output voltage per channel: 0 V to 32 V
• Max. output current per channel: 0 A to 3 A
• Standard interface: USB (VCP/TMC); options: LAN (LXI), WLAN, digital trigger I/O (4‑bit)
• Front connectors: 4 mm safety binding posts

Features & benefits

• Galvanically isolated, earth‑free channels – each channel is electrically isolated from chassis ground for safe series/parallel combinations and to avoid ground loops with complex DUTs.
• Parallel and series operation – channels can be combined in series for higher voltage (up to 96 V with NGE103B; up to 64 V with NGE102B) or paralleled for higher current (up to 6 A with two channels; up to 9 A with three channels).
• Per‑channel protection – adjustable OCP (electronic fuse), OVP and OPP; on limit the channel switches off and displays a message; FuseLink allows linking overcurrent protection between channels.
• Clear status display – 3.5" QVGA (320×240) color display with color codes for CV/CC/inactive and a blue background for the active setting.
• Measurement and special functions – integrated measurement of voltage, current, power and energy; EasyArb arbitrary function; FuseLink and fuse delay.
