Serial AC Power Sequencer
90-200-001
Each power outlet can be programmed to switched on in sequence with a specific timing delay. The delay can be staggered to ensure that order dependent systems - like PXI - can be switched on and off in an orderly way with just one operation. A staggered start up also limits the inrush current associated with the powering up of equipment, including earth current inrush, placing less stress on cabling and leakage breakers. Power on or off instructions can be initiated from either the front panel switch or via the serial interface.

Handheld Micro-Ohmmeters
RMO-H Series
The RMO-H is battery operated and handheld micro-ohmmeter. It is designed for a variety of applications for contact resistance measurement of non-inductive test objects. Typical applications are accurate testing of:medium and high-voltage circuit breakers,disconnecting switches,high-current bus bar joints,cable splices,and different high-current links.Even more, it accurately measures in high-induction filed environments and substations, as well as in factory testing.RMO-H Series contains six models in total, divided in 2 sub-series depending on the test leads length requirement and the battery type:RMO-H1, RMO-H2 and RMO-H3 models are intended for use with short cables (e.g. 1,3 m / 3 m / 5 m). The 1-cell Li-Po battery with 8200 mAh capacity provides output voltage up to 4,1 V DC.RMO-H21, RMO-H22 and RMO-H23 models are ideal for applications where test leads with lengths > 5 m are required. The high output voltage (up to 8,3 V DC) is provided by 2-cells 4100 mAh Li-Po battery.The test current is regulated and can be selected in a range of 1 A to maximum 300 A, depending on the maximum test current rating:RMO-H1, RMO-H21 models – up to 100 A DCRMO-H2, RMO-H22 models – up to 220 A DCRMO-H3, RMO-H23 models – up to 300 A DC.Unlike many other handheld micro-ohmmeters available on the market, our instruments have regulated and user-selectable test currents. Therefore, RMO-H instruments generate an automatically regulated test ramp with stable and ripple-free current during measurement. These revolutionary characteristics in a handheld micro-ohmmeters technology are possible by using sophisticated Li-Po batteries. Consequently, modern battery technology enables you to do multiple measurements, and a full day of testing without recharging the battery.With all RMO-H models, it is possible to make tests on Both Sides Grounded testing objects, in an increased safety environment. Finally, these features in combination with a user-friendly interface (1-click to measure) significantly speed-up testing procedure and make it safer.These instruments store up to 1000 measurements on the internal micro SD card.Our free DV Win software communicates with the RMO-H micro-ohmmeters via a wireless Bluetooth interface. Furthermore, it allows you to download test results, analysis and generate fully configurable test reports.

Circuit Breaker Test Equipment
DV Power has released a new generation of circuit breaker test equipment for condition assessment of medium and high voltage circuit breakers.Field-portable instruments with standalone or PC controlled functionality, allow performing various tests during circuit breaker manufacturing, commissioning and maintenance stages.Applications supported by the DV Power test equipment include measurements of:Contact resistanceDRM (dynamic resistance measurement)Coil resistance and coil current (IEC 62271-100)Mechanism charging time (IEC 62271-100)Minimum trip voltage (IEC 56, ANSI C37.09)Undervoltage release (IEC 60694)The timing of a circuit breaker’s main, auxiliary and pre-insertion contactsSynchronization between the contactsMotion and velocity“First trip” testThe essential part of a circuit breaker condition assessment is the ability to compare the latest test results with the previous testing. Accordingly, our instruments store measured values and compare them to a manufacturer’s limits. Also, a fingerprint obtained in this way can be used at a later stage as a reference during subsequent measurements. In order to obtain an accurate comparison, the tests need to be performed using identical test parameters. Consequently, any deviation and change in the test results may indicate the circuit breaker condition deterioration. Even more, to overcome this issue, DV-Win enables test plans and graph overlay features.Finally, as a final result of a circuit breaker maintenance process, the DV-Win provides analytical tools and customized report creations.

Multiple Channel Burn In Power Supply
MCPS
The most important features of this burn in power supply is its ability to hold a constant output for each channel even in the event that a unit under test on one channel may short and fail. Since each channel has it''s own transformer, no glitches or voltage spikes can get into any of the other channels. This image shows the results as the second channel from the left is shorted with a small wire and the circuit breaker pops out. Used for burn-in testing and other timed testing where power isolation is required. Very basic simple circuit, see schematic below. Cleans and frees up benchtops, burn in racks and work space clutter. Available in benchtop or rackmount.
