Cynergy3 Components have recently launched a new variant of their high voltage reed relays - these having high insulation resistance of 1x10E14 Ohms. Available in PCB mount format with either PCB connections or flying leads, there are a range of 5, 12 or 24Vdc coil versions, with either tungsten or rhodium contacts.

* 10kV or 15kV Isolation
* Low Contact Resistance
* PCB or Flying Leads Connections
* Ideal for sensitive test and measurement circuits which require low leakage current losses

Very high isolation voltages - up to 15kV - are achieved through the use of high vacuum reed switches with either rhodium or tungsten contacts which make these relays suitable for high reliability applications, such as cardiac defibrillators, test equipment and high voltage power supplies. The rhodium contact relays have low contact resistance, while the tungsten contact relays can switch higher voltages.

Typical applications for these DH-R Series relays include cardiac defibrillators, test equipment, high voltage power supplies and other high reliability equipment.

Cynergy3 Components has introduced the D200 Series high voltage reed relays which combine a high power 200W switching capacity with isolation of 7kV across the contacts.

The D200 relays come in the same package and pin-out as the popular D Series. The switching performance is achieved through the use of high vacuum reed switches with tungsten contacts. Typical D200 Series applications include test equipment, high voltage power supplies, medical equipment, or any application requiring increased safety margins on the switching power ratings.

D200 Series relays come with Normally-Open (NO) contacts. Models are available with 5V, 12V and 24V coil operation. The maximum switching voltage is 2.5kV. The contacts are capable of switching 3Adc, or carrying a maximum current of 5Adc.

Cynergy3 Components has been manufacturing high voltage reed switches and reed relays for over 40 years. All relays are assembled in the state-of-the-art facility located in Wimborne UK. Cynergy3 Components also manufactures a wide range of sensor products including Liquid Level, Liquid Flow and Pressure Sensors. All products are stocked and available through distributors worldwide.

Simon Dear, Sales & Marketing Manager at Cynergy3 Components comments: “The D Series relay has long been the favourite choice for engineers with demanding high voltage applications. The new D200 Series provides engineers with a solution for critical applications where increased power handling capability is a prime concern”.

For applications where high current loads need to be switched but power is limited, Finder’s 67 Series 50A, high capacity PCB relay efficiently minimises coil power dissipation.

The relay has a high continuous current contact rating of 50A, and peak current of 150A (5msec), providing two and three pole NO double break contacts.

Developed for inverters with DC inputs up to 1500V and AC outputs up to 690V, and with a 3mm or 5.2mm contact gap according to VDE 0126-1-1, EN 62109-1 & 2 regulations, the 67 Series satisfies the arduous requirements of equipment designed to meet the increasing demand for solar energy, particularly in remote locations and at high altitudes (up to 4000m above sea level).

The relay is also suitable for use in photovoltaic inverters, battery-operated or portable systems, domestic appliances and for 3 phase motor loads up to 7kW.

The Energy Saving Mode feature allows for coil operation in ambient temperatures up to 85C with minimum holding power of just 0.17W

The added air circulation provided by the 1.5mm stand-off between the relay and PCB aids temperature regulation.
