Information on NEXTYS NISO-20

The NEXTYS NISO-20 is a high-performance, ultra-compact DIN rail DC/DC isolation module engineered to provide outstanding galvanic separation of 3 kV AC (4.2 kV DC) while delivering an impressive power capacity of over 800 W. Designed with a wide 10 to 55 V DC input range, it functions similarly to an AC transformer by directly tracking input voltage to output, making it extremely versatile for isolating DC networks and preventing ground loops. Operating at an exceptional peak efficiency of over 96%, the NISO-20 minimizes power dissipation, allowing it to fit into a space-saving aluminum enclosure measuring only 54 mm in width.

Beyond its robust isolation capabilities, the module features comprehensive monitoring tools including an INPUT OK green LED, OUTPUT OK green LED, an OVERLOAD red LED, a visual 4-LED amber load bargraph, and a dry-contact DC OK relay for system telemetry. System safety is enforced via automated thermal protection and a current-limiting Hiccup mode with auto-restart for short-circuit and overload conditions. Engineered for harsh industrial environments, the module supports a wide operating temperature range from -40 °C to +70 °C and offers seamless parallelability with natural current sharing, making the NEXTYS NISO-20 a highly reliable choice for industrial automation, renewable energy, and telecommunication systems.
