Programmable dc electronic loads include e 300% peak-overpower capability
The 63200A series high power DC electronic loads are designed for testing a wide range of power conversion products including ac/dc and server power supplies, dc/dc converters, EV batteries, automotive charging stations, and other power electronics components. These units can be synchronously paralleled up to 240 kW and dynamically synchronized for generating complex multi-channel transient […]
Testing PV inverters
A photovoltaic, or PV, inverter converts the dc output of a solar cell or array into ac that can feed directly into the electrical grid (Grid Tie) or be used by a local electrical grid (Off-Grid). Solar PV inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking (MPPT) and […]
Batteries, battery analyzers and battery testers
The Leyden jar, invented by the Dutch physicist Pieter van Musschenbroek in 1746, preceded what we today call the battery. Originally, “battery” denoted several units connected in series or parallel. Thus, there could be a battery of Leyden jars. Actually, the Leyden jar works on a principle completely different from that of a battery. It […]
