Spring clamp connection

"The control cabinets in the tunnel are only 1.2m high. Therefore, they require very simple wiring. Emparro power supply units make this possible: they are connected with spring clamp terminals," say Timo Korsch, physics engineer at European XFEL. The terminals are designed using push-in technology so connection wires can be mounted in the front without using tools. The contacts are permanent and never need retightening.

Thanks to their efficiency rating of up to 95%, Emparro power supplies only lose a small amount of energy. This means they don't dissipate much heat. "Less heat dissipation means less cooling is required in the air-conditioned control cabinets which saves energy and lowers costs," says Korsch.
