Size the Continuous Load, Startup Demand and Cabinet Temperature Around Hirschmann RPS 80 EEC Part Number 943662080 Before Supplying Industrial Ethernet Equipment
Hirschmann RPS 80 EEC Part Number 943662080 is a DIN-rail power supply with adjustable 24-28 V DC output. The catalog provides both AC and DC input options, short-duration output capability and temperature-related derating, giving designers concrete values for a network power budget.
A useful supply choice starts with the load
For Hirschmann RPS 80 EEC Part Number 943662080, add the normal current requirements of the connected devices and examine their startup demand separately. The catalog's brief higher-current capability is time-limited; it should not be used as a continuous output rating for an overloaded network panel.

The adjustable output of Hirschmann RPS 80 EEC Part Number 943662080 lets the designer review the supply setting against connected equipment limits. Check the voltage at the load under the intended conditions, especially where cable length contributes to voltage drop. Any adjustment must remain within each device's permitted supply range.
Thermal and terminal planning
The documented operating range for Hirschmann RPS 80 EEC Part Number 943662080 reaches +70 C, with derating beginning at 60 C. Calculate the usable output for the actual cabinet temperature using the manufacturer instructions. The temperature beside a heat-producing component can differ from the room temperature.
- Three-pin spring-clamp input connection.
- Four-pin spring-clamp output connection.
- DIN-rail installation with a 32 mm wide housing.
- IP20 construction requires an appropriate installation environment.

The source states that Hirschmann RPS 80 EEC Part Number 943662080 units can be connected in parallel. A resilient supply design still needs the prescribed wiring, load-sharing or isolation arrangement and suitable fault behavior; placing two supplies together does not establish a complete redundant system.
Commissioning evidence for the power circuit
During acceptance of Hirschmann RPS 80 EEC Part Number 943662080, record the input source, output setting, connected load and normal indicator condition. Check both steady operation and the expected startup event using the site procedure. The DC OK and Overload indications provide useful local status information.
