Surge protector for DC power source protection in energy infrastructure systems, 45 V DC RSP-SPLH-2-7A 2616597

Professional protection for DC power sources

The RSP-SPLH-2-7A surge protector is an advanced solution designed specifically for energy infrastructure systems utilizing DC power. The device effectively protects sensitive control and measurement electronics from the destructive effects of surges that may occur in power networks.

Operating parameters and performance

Model RSP-SPLH-2-7A operates at a rated voltage of 36V DC, with the capability of continuous operation up to a maximum voltage of 45V DC. This voltage range is typical for modern control and automation systems in energy infrastructure.

A key feature is the response time < 1 nanosecond - this is an extremely fast reaction that practically disconnects the harmful surge from the protected circuit immediately. This ensures that even the shortest high-voltage pulses do not have time to damage the connected electronics.

The device is characterized by high endurance parameters. An impulse current of 5 kA for a 10/350 µs pulse allows for the absorption of energy from strong atmospheric discharges. A rated discharge current of 10 kA for an 8/20 µs pulse provides effective protection against frequent, smaller network surges. A protection level of 180V guarantees a safe output voltage, protecting loads from damage.

Construction and compatibility

The surge protector has been designed for easy integration into existing installations. Mounting on a TH-35 mm DIN rail allows for quick and secure placement of the device in electrical switchboards, control cabinets, or automation panels.

The compact design (net weight 900g) does not excessively burden the installation, while simultaneously providing solid mechanical stability. Operation signaling was intentionally omitted - the device acts as a "silent guardian," protecting the system without the need for additional signaling wiring.

The device meets ETIM class requirements for DC power line surge protectors for IT/I&C systems, confirming its professional purpose for advanced energy applications.
