Two power supply ranges from WAGO provide additional functionality to suit a wider range of applications such as vending, slot and coffee machines, as well as heating controls and ventilation systems.

The new EPSITRON® ECO range includes a compact, cost-effective option, while the EPSITRON® CLASSIC series has undergone a redesign, making the device 45 percent slimmer yet retaining its powerful functionality.

EPSITRON® ECO offers a robust power solution for 24 VDC applications where control cabinet space is at a premium. It also conforms to EN 60335, bringing industrial power supply capabilities into consumer appliances such as vending machines and cash machines.

The power supply features a robust metal housing to withstand rugged treatment and can be mounted on a DIN-rail, or screw fixed horizontally, vertically, or overhead.

The power supply provides a wide input voltage range of 90 to 264 VAC. This flexibility allows a mass-produced machine to be operated on different power networks in Europe, America or Asia with no need for conversions or modifications. In addition, its high input voltage range means increased tolerance to voltage fluctuations, leading to high reliability.

Voltage availability is indicated via a green LED, while a red LED indicates an overvoltage. This simplifies start-up and provides maintenance personnel with a clear indication of system or machine status.

WAGO’s redesigned CLASSIC power supply is slimmer than previous generations and offers up to 93 percent efficiency. A temperature range of -25 °C to +70 °C makes it suitable for applications including building automation, process control and industrial machines and equipment.

Ranging from 25 W to 960 W, the CLASSIC power supply provides 12, 24 and 48 VDC nominal outputs. The power supply is universally compatible with all standard power grids found worldwide.

EPSITRON® CLASSIC’s optional integrated TopBoost function provides a brief power surge in the event of a secondary short circuit or overload by multiplying the nominal current, thus ensuring effective secondary side fusing via traditional low-cost circuit breakers for improved safety.

Connections on the ECO and CLASSIC power supplies are kept secure with WAGO’s CAGE CLAMP® Spring Pressure Connection Technology, which provides fast, vibration-proof and free from maintenance termination of solid, fine-stranded or ferruled conductors.

This not only ensures that wiring is much faster, but that connections are indefinitely held in place even in extreme environments, for example in marine, offshore, or heavy industrial applications.
