Electromagnetic Type; Actuator Voltage 12 to 24 VDC; Load Switching Current 3 to 110 A RMS; Maximum Switching Voltage 4 to 50 kVA pioneer in the development of the original high voltage vacuum relay, Jennings Technology is still recognised around the world as a leading manufacturer of high voltage relays today. Jennings’ relays are noted for fast operating speeds and the ability to withstand high voltages and carry heavy currents (at frequencies up to 75 MHz), while maintaining low and stable contact resistance.Jennings vacuum relays are available in SPST (Single Pole, Single Throw) normally open (N/O) and normally closed (N/C) models up to 33 kV, as well as SPDT (Single Pole, Double Throw) configurations up to 30 kV and gas filled relays up to 70 kV. Latching relays are available in some models.The reliability of Jennings vacuum relays is second to none; many of these relays have guaranteed life ratings set in the multi-million cycle range. The relays' reliability coupled with their small size and high power handling characteristics make the use of Jennings relays in any mission critical application an obvious choice. Many of Jennings relays are fully Mil-Spec rated.Vacuum is the ideal dielectric for high voltage relay switching. It has extremely high voltage breakdown characteristics, a fast recovery rate (up to 10 kV per millisecond) and it provides an absolutely inert and non-reactive environment for switching contacts. If a load is switched, an arc will form. This arc will have a very low voltage of 18 to 23 V and be quite stable in comparison to an arc in air, which is another advantage of vacuum. The vacuum relay constant arc voltage acts as a current limiter and, in combination with the short arc time, generally offers less wear than other types of relays.Key Features: Extremely High Voltage Breakdown Characteristics Available in SPST N/O and N/C Models as well as SPDT Configurations Latching Relays Available in Some Models Contacts Remain Oxidation-free Small, Low-mass Actuators for High Operating Speeds Very Low Arc Voltage: 18 to 23 V Less Wear Than Other Types of Relays Test Voltage (at 60 Hz): 4 to 50 kV Peak Max. Continuous Current: 3 to 110 A RMS Applications: Airborne, Mobile and Marine Communications Equipment; Antenna Coupling; Tap Changing on RF Coils; Transmit/Receive Switching to an Antenna; Switching in Pulse-forming Networks; Heavy-duty Power Supplies

35 to 450 A RMS; Single Terminal; 28 to 45 kV; Mechanical Life 0.5 to 2 Mio. OperationsJennings Technology’s series of vacuum interrupters handle a wide range of voltage and current interrupt levels, and high-quality and highly reliable interrupters are available for the utility and industrial markets.Current interruption in a vacuum is recognized as the ideal switching technology in the medium voltage range, and it is also applied in high-voltage and low-voltage applications. Excellent switching capabilities and compact design make vacuum interrupters the most economical switching device solutions possible.Jennings vacuum interrupters feature an evacuated ceramic insulating envelope surrounding two contacts, one fixed and one movable. The movable contact is operated from the outside through a metallic bellows. Contacts are typically a copper alloy that is developed for use in AC voltage applications. The end plates are made of stainless steel or copper.With these features, vacuum interrupters can be expected to last the life of the equipment in which they are installed. Their interruption mechanism is independent of the current magnitude, so interruption can normally be anticipated at the first current zero with no restriking, as the dielectric strength of the contact gap recovers more rapidly than the recovery voltage can rise.Vacuum dielectric enables the interrupters’ contacts to be arranged close together, so circuit interruptions can be designed in a smaller envelope. With current interruption occurring in a vacuum, all arcing is confined within the vacuum interrupter body, so Jennings interrupters are noise-free and flash-free, avoid contact contamination as oxides and corrosion layers cannot form in vacuum, and they do not emit any greenhouse or toxic gases.Key Features: Long Life, High Reliability Controlled Contact Erosion Results in Virtually Maintenance-free Operation Fast Interrupting Speed Rapid Dielectric Recovery High Cycle Withstand Voltages Robust, Compact Design Environmentally Friendly Atmospheric Contact Contamination is Eliminated Noise-free and Flash-free Applications: Load Break Switches; Contactors for Industrial and Motor Control; Capacitor Bank Switching; Circuit Breakers; Specialty RF and DC Applications

30 to 4,000 pF; 1.8 to 36 kV Vacuum capacitors for high voltage and high frequency applications offer long, maintenance-free service life and the ability to withstand transients that destroy other types of capacitors. Vacuum assures oxidation-free surfaces and a dielectric that is self-healing when subject to transient over-voltage conditions. This series of variable vacuum capacitors offers capacitances of 30 to 4,000 pF, withstanding working voltages at 50/60 Hz in the range of 1.8 to 36 kV. In addition to this working voltage, a value for AC test voltage is quoted in this series’ product specifications. The maximum operating current for vacuum capacitors is limited by temperature rise and working voltage. A current vs. frequency chart is provided for each capacitor. If none of our standard catalog models meet your needs, our supplier`s engineers are happy to work with you to design a custom solution that meets your specific requirements. Capacitance Tolerance: For this series of variable capacitors, the low-end capacity will be equal to or less than minimum rating. The capacitance change is substantially uniform with rotation, and there are no capacitance reversals. Capacitance is within ±10% of the nominal value of the curves shown in the data sheet (capacity vs. turns), in the linear portion of this curve. Torque/Direct Pull: In variable capacitors, the linear sliding motion of the moving electrode assembly is converted to rotary tuning via a threaded shaft. The torque values given in the tables are the maximum torque needed to reach minimum capacitance when rotated with a standard lead screw; the torque required to tune away from minimum may be less than half this value. For most variable capacitors, direct pull tuning is an available option to rotary tuning. Maximum required direct pull force values are also given in the tables. Capacitance range end-stops are built into every variable capacitor. It is recommended that the user install their own external stops to prevent damage from gear-reduction drives. Mechanical Life: The mechanical life of variable capacitors is related to length of stroke, speed of operation, bellows material and total number of cycles. Extensive mechanical life tests have been run, operating units for complete cycles from maximum to minimum and back to maximum capacity covering 95% of the full stroke of the movable plates. Capacitors with a large bellows and a short stroke will have the greatest life expectancy under cycling operation. Our most recent variable capacitor models are rated for >2 million cycles, ideal for the semiconductor processing industry. Testing Standards: All capacitors are factory tested for dielectric strength on a 100% basis prior to shipment, using a low current, high potential source at 60 Hz voltage. Upon customer request, certified test reports will be made available.
