Power supply offers protection in extreme environments

Phoenix Contact says the new Quint Power Plus version is the solution for complex applications even under extreme ambient conditions.

The power supply with a nominal output current of 40 A has a protective coating and ATEX and IECEx approval for potentially explosive areas (zone 2). With an integrated decoupling MOSFET, the power supply can be directly connected in parallel, thus increasing system availability. In addition, with its SIL 3 approval the Plus version ensures high operational safety.

The Quint Power Plus version has double OVP (overvoltage protection) and thus protects the system against voltage increases. In the event of a fault, the corresponding output is switched off to protect the loads against over-voltages and the power supply connected in parallel ensures reliable supply.

The possible uses primarily include applications in the process industry, shipbuilding, the energy sector and even the railway industry. The robust input side with an input voltage of 85 V AC ... 264 V AC and an integrated gas discharge tube provides a high level of immunity (up to 6 kV) and ≥20 ms mains failure buffer time.

The powerful output side with a static boost of 45 A, dynamic boost of 60 A, and SFB Technology enables easy system expansion and provides reliable starting of difficult loads and tripping of standard miniature circuit breakers.

Due to comprehensive signalling, preventive function monitoring with analogue, digital, and relay contacts can report critical operating states at an early stage before faults occur. The new Plus version is rounded out by its unrivalled wide temperature range of -40°C to +75°C for use under extreme ambient conditions.
