The MTDR300, a NEW stand-alone 3-phase instrument designed to find faults in cable networks

The MTDR300 provides several low-voltage and high-voltage methods of cable fault location.

• Full 3-phase TDR/pulse echo capabilities
• Allows simultaneous testing of up to 3 phases
• Operates by battery or main power supply
• And much more!

A multi-faceted unit!
As a stand alone TDR, it provides full pulse echo capabilities. When used in conjunction with an impulse generator and arc reflection filter, it provides the following:

• Arc reflection
• Arc reflection plus
• Impulse current
• Voltage decay modes (with a dc source)

SMT Connector Powers LEDs From Underside Of Board

Tyco has introduced the SMT thru-board connector, which supplies power from the underside of an FR4 or aluminium-clad PC board, eliminating issues of dressing wires on the top side of LED boards. The two-position through six-position connector surface mounts on top of the board, passing through the board to present an underside interface. The connector mates with standard Mini CT connectors. The inverted design allows simpler assembly and installation of solid-state LED lighting in architectural, residential and commercial applications. The Mini CT connector is rated for three amps per contact, on 24 AWG wire. A space-saving low-profile design and rounded corners minimise shadowing. The connector fits through a hole or notch in the board. High-temperature materials allow the connector to be reflow soldered, while a flat-top surface provides compatibility with vacuum pickup. The connector uses surface-mount hold-downs to provide stability during mating and unmating. With UL listing...

Electromechanical Relays (EMRs) vs. Solid State Relays Comparison (SSRs)

Image
Electromechanical Relays (EMR) Pros (Advantages) Lower initial cost compared to solid state relays. Provides complete electrical isolation. Tolerates high current & voltage transients. Insensitive to electromagnetic interference (EMI) / radio frequency interference (RFI). Higher open resistance (air gap). Lower closed resistance. Available with many poles/circuits (up to 8 or more). Many different circuit configurations available. Multiple packaging & feature options. Most typical failure mode is open. Electromechanical Relays (EMR) Cons (Disadvantages) Higher control (coil) power consumption. Contact arcing can cause pitting & eventual open/short failure. Contacts can be affected by corrosion, oxidation or contamination. Contact bounce possible due to shock & vibration. Generates electromagnetic interference (EMI) / radio frequency interference (RFI). Can be orientation sensitive. Can be affected by external magnetic fields. Subject to mechanic...
