Power supply units provide customisable solutions

The power supply units give control engineers improved configuration and diagnostics to ensure reliable power to the control system.

The new generation includes near-field communications (NFC), real-time monitoring, coordinated surge protection, and a configurable DC output characteristic. With secured NFC, the power supplies can be configured while still in the box.

User-definable settings allow engineers in the field to monitor DC current, power, or voltage in real time using a 4mA–20 mA analog output.

Engineers can also add tamper-proof security to the QUINT power supplies by locking out the push buttons on the front panel and creating a user-defined password. In addition, operating hours, DC input voltage, overvoltage, and temperature derating can also be monitored with dry contact outputs.

The units use established QUINT features like Power Boost and Selective Fuse Breaking (SFB) technology. SFB technology delivers six times the rated current for up to 15 milliseconds to selectively trigger standard circuit breakers. The units offer static boost with up to 125 percent of the rated current, allowing engineers to expand the system.

For starting heavy loads, the power supplies feature dynamic boost with up to 200 percent of the rated current for up to five seconds.

The DIN rail QUINT4 power supplies are available from Mouser Electronics in single- or three-phase models with widths of 36mm to 70mm. All units include gas discharge tubes to protect against transient voltages.
