Voltage Protection
Are solid state voltage sensing relays with electromechanical output contacts built in a fully draw out case format. Designed for application on AC & DC voltage systems, these relays are ideally suited to monitor power supply voltage levels wherever high accuracy and reliable, maintenance free operation is essential. All power to operate the relays is derived from the sensed input voltage therefore an auxiliary supply is not required.

ESD Protection
Protection against electrostatic discharges (ESD) is part of EMC Immunity (Electro Magnetic Compatibility) requirements. It is the ability for equipment to properly operate in its electromagnetic environment by limiting the reception of electromagnetic energy that may cause physical damage. ESD can be either conducted under the form of a transient voltage or can be radiated due to its fast rising time: powerful harmonics will generate erratic behavior by the application by coupling with other signals. Printed circuit boards must be protected against the effects of electrostatic discharge.
