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.

Voltage Monitoring, Timer Delay-on -off, 4 Pole
MTDV4 Relay
Plug-in electronic voltage monitoring relay with optional delay-on and delay-off timer function and four change-over contacts. The delay time is adjustable with a lockable knob (either delay-on or delay-off, the other delay is fixed). The relay can also be supplied with fixed time delays (no knob). The pull-in voltage and drop-out voltage are both adjustable via internal screws. The relay can also be supplied with a fixed pull-in and drop-out voltage. Suitable for monitoring DC voltages.

Solar PV Installation Testers
Given the growth of solar installations (also called PV installations) worldwide, it comes as no surprise that the safety and quality of these systems is being considered at an international level. In particular, the presence of a possible fire hazard or electrocution creates major risks when a PV installation is not installed correctly. This indicates that monitoring PV installations is a necessity. A standard quality control during installation and periodic inspection is therefore of enormous importance for the safety of both installer and user.

Current Protection Relay
The main earth fault protection relays in distributions systems, power stations & large manufacturing / processing plants can fail to detect a high impedance break down to earth causing hazard to human life & potential damage to plant & equipment. In these & other situations demanding extra sensitive earth fault protection, using solid state techniques, can be applied to detect earth currents down to 0.5% of the CT nominal current.
