N4A

Programmable DC+AC coupled Power Sources 3kVA to 67kVA

The N4A range of Programmable AC and DC coupled Power Sources use an innovative combination of high-speed power stage switching and 6-legged output stage to achieve a rugged, low distortion supply. This technique combines the flexibility of a switched design with low distortion normally achieved only with a linear design. DC and AC coupled, with a full power bandwidth from 0.01Hz 1kHz and small signal bandwidth to 10kHz, the N4A series provide power development and test engineers with a hugely flexible power source. The N4A is also the source used in N4L Harmonic and Flicker test systems, where its low dynamic output impedance combined with our accredited impedance networks, ensure total system impedance is compliant with IEC61000-3-3/11 standards. Used in conjunction with our IECSoft PC software, the N4A series also provide a compliant solution to 61000 Immunity standards.
