 R&S NGE100 channel switching power supply series
Rohde & Schwarz has launched a new series of quiet power supply series with variable channel switching.

The two-channel R&S NGE102 and the three-channel R&S NGE103 are easy to operate and aimed at a wide variety of applications, from education to R&D labs to manufacturing. Fan control ensures that they are quiet. The power supplies deliver up to 33.6 W output power per channel with low ripple. They offer a per-channel output voltage of up to 32 V and output current of up to 3 A and the galvanically separated channels can be switched in series or in parallel to increase either the output voltage or the output power.

This means that even complex switching operations can be performed without grounding problems. Users can switch the channels in series or in parallel. Two channels switched in series deliver an output voltage up to 64 V, three channels up to 96 V. When the channels are switched in parallel, the instrument supplies a maximum of 6 A for two channels and 9 A for three.

The power supplies also offer configurable overload protection where the maximum values for current, voltage and power configurable for each channel

The R&S NGE100 provides very flexible protection options. Users can enter maximum values for voltage, current and power separately for each channel. The electronic fuses can also be linked with other channels. All linked channels will be switched off as soon as one of the linked channels reaches a limit. Users can define a delayed response time to prevent the power supply from switching off in the event of a short current spike.

The small, compact power supplies can be used on the benchtop or mounted in a 19" rackmount (with a rack adapter). They can be remote controlled via the integrated USB interface or optionally via LAN or WLAN. A digital trigger option is also available. A key code activates the options.

The power supplies are available now with prices starting at EUR 650.
