Got an Idea?

We are bringing, in an average four new devices to the market per month. Below is just an example of switches/drivers that we keep in our stock in small quantities and ready to ship them at once. For your unique application that required a different voltage, current or speed, do not hesitate to send us an email to: info@vsholding.com for any additional information, delivery schedule and prices.

The Solution

 There are several ways to solve the problem of contact bounce (that is, to "de-bounce" the input signal). Often the easiest way is to get a piece of equipment that is designed to accept "bouncy" input and EDR’s made Solid-State Relays are the solution. (Learn more)

EDR’s family of “D9G”

Solid State Relays/Switches designed for speed and high power. The D9G relays/switches have the capacity to switch efficiently DC or AC and can deliver a megawatt power in a single pulse. They were designed to operate at wide frequencies, DC to 800 KHz. High switching frequency allows it to deliver power with high precision. At 8 KHz PWM can be controlled in wide range for 1% to 100% duty cycle and it is an ideal choice for high-speed and high-accuracy applications such as motor control, SMPS (switch mode power supplies), laser diode driver or a high frequency ultrasound cleaner.(Learn more)

EDR’s family of “T”

Solid State Relays/Switches designed for speed, the T3SxxDxx and more powerful T7SxxDxx relays/switches have the capacity to efficiently switch DC or AC and can deliver a single lesser than 0.7 μS pulse width. The “T” family SSR, a half-bridge MOSFET/IGBT driver is designed to operate at frequencies up to 800 KHz (8 KHz PWM for 1% to 100% duty cycle) and is an ideal choice for high-speed applications such as motor control, SMPS (switch mode power supplies), laser diode driver or a high frequency ultrasound cleaner. The “T” relay/switch can be used in pairs for a full-bridge operation, or triplets in three-phase brushless DC motor driver applications. A 1.2 MHz relay/switch is also available with ability to deliver a powerful a > 50 nS pulse. (Learn more)

 Full-Bridge (H-switch), Isolated, Bidirectional Drivers

The second generation of the low-cost drivers is an all-voltage, full-bridge (H-driver) drivers designed to deliver up to 1,200W in a small D2- size or DIN mountable enclosures. Both types is used in applications to control various devices such as intelligent toys, appliances, power tools, relays, solenoids, dc and bipolar stepping motors. Full 3,750V input-output isolation allows save interfacing directly to a low-power CMOS (or TTL) logics. The enable input can be simply paralleled with a brake control input (large varieties of EDR made switches can be used in such application.(Learn more)

 The first 1.5W, 3W and 6W iUPS-DC/DC with isolated converters and internal Lithium-Ion batteries for the most demanding bio-medical and industrial applications

The EDR/VSholding's iUPS-DC/DC converter provides a complete solution for bio-medical and industrial needs for protecting vital data gathering in cases of power failure and surge protection. The iUPS is designed to deliver up to 1.5W, 3W or 6W at all industrial standard output voltages to any peripheral device. (Learn more)

UPEL-2500

The UPEL-2500 is a universal tool for testing power sources in diverse industrial production, repair shops and instrumentation laboratories. The system offers up to four times the power rating of existing loads in the same or higher cost ranges. The operating principle is based on a high-speed current transformer providing feedback to powerful lateral MOSFETs, ensuring low EMC, susceptibility and delivering precise control of the UPEL-2500’s output characteristics.

Family of 50/60Hz Powerline Comb notch filter expanded

60/50Hz notch comb reject filterLine Power adaptive filter
The members of the multi-notch, comb reject, filter family has expanded by the introduction of our PLAF-01 (power line adaptive filter). This is a stand-alone unit created for use in the detection of natural electromagnetic waves at remote locations and seismic data collection, biomedical and other scientific and industrial applications. EDR's notch filter is a very unique device. It substantially reduces electrical noise caused by power sources without altering the waveforms of an input signal. The internal phase-lock loop circuitry monitors power line frequencys and is automatically synchronizes to any frequency in the range between 47Hz and 70 Hz.
