Description

NGM-COM2B | Bundle power supply, bidirectional, DC, 20V / 3A / 120W, 2 channels, USB, LAN (3638.4472P87)

The two-quadrant architecture of the NGM200 series of power supplies from Rohde & Schwarz enables it to be used as a source and a sink for simulating batteries and loads. Rapid load changes, e.g. B. when changing from sleep mode to active mode of mobile devices, can be absorbed by the short settling time. The devices are available with one channel (NGM202) or as a 2-channel device (NGM201) with an output power of 60 W per channel. The outputs are floating and galvanically isolated.

The power supply units of the NGM200 series are protected against overload and short circuit. A 6½-digit digital multimeter is integrated to measure voltage, current and power. With the fast settling time of <30 μs , the very low overshoot even with sudden load changes and the fast impedance control , the power supply units are ideally suited for powering IoT devices and other battery-operated devices. With a sampling rate of 500 kS / s , very fast voltage and current changes can be recorded. An optionally available battery simulation function imitates the real conditions of a battery supply for a test item.

Fast load regulation

Battery-operated consumer electronics devices or cell phones and IoT devices require very little power in sleep mode. However, the current rises suddenly as soon as the device switches to transmit mode. The power supply of such test items must be able to handle load changes from a few μA up to the ampere range without causing voltage drops or overshoots. With the NGM200 power supply units, the user can determine how these rapid load changes are to be regulated. The standard setting "Fast" is optimized for speed and achieves recovery times of <30 μs.

Minimal ripple and low noise

The power supplies of the NGM200 family have linear control and are ideal for sensitive test objects. Many power supply units usually react to sudden load changes with overshoots and slow recovery times. Thanks to the optimized control loop, the NGM200 series, on the other hand, achieves settling times of less than 30 μs.

This package includes the following options:

  • K103 Digital Trigger I / O
  • K104 Digital Voltmeter Functionality
  • K106 Battery Simulation
