Regenerative Grid Simulator /AC Source
NHR’s Regenerative Grid Simulator 9410, or Grid Emulator, is a bidirectional AC source ideal for simulating complex power disturbances for testing micro-grid such as Solar/PV inverters, ESS, V2G, the utility grid, and chargers. A wide-range of AC conditions can be emulated including phase imbalance, voltage sag, frequency changes, and harmonic injection.
Applications include grid simulation/emulation for testing PV inverters and other grid-tied products for compliance to IEEE 1547, UL 1741, and global industry standards in addition to military applications.
- 8 power ratings – scalable from 4 to 96 kW
- Dual AC voltage range – 175, 350 VAC at 30 to 100 Hz AC
- Dual DC voltage range – 200, 400 VDC
- Regenerative discharge (load) High efficiency > 90%
AC Source with HIVAR
NHR’s AC Source with HiVAR (9420) is a general purpose AC source offers more than twice the apparent power capability per kW than traditional AC sources. Traditional AC sources list only their VA rating leaving it up to the user to figure out how much true power remains after reactive power reductions. In many cases, that reduction is substantial and then requires selecting a much larger VA-rated source than originally anticipated. Its wide operating envelope results in substantially more useable true power.
Applications include designs over a wide range of input voltages and frequencies for military applications such as magnetic devices, ATE, power-line disturbances, power conversion, UPS, PDU, data centers, etc.
