  • Panasonic Relays in EV charging stations
    January 14, 2016
    The global adoption of electric vehicles underlines the need for quality relays and components to ensure a robust electric vehicle supply equipment (EVSE) infrastructure. According to the International Energy Agency, the number of electric vehicles worldwide in 2020 is projected to grow to 20 million. As the market expands, the demand for more electric vehicle charging stations is becoming increasingly necessary.
  • Increasing Load Capacity in PhotoMOS® Relays

    PhotoMOS Relays inherently have a limited DC load, however, by changing the output terminal connections, 6-Pin DIP and SOP type PhotoMOS Relays can withstand a higher load capacity.

    What Is UL 1604?Engineers who specify electrical products for industrial equipment tend to have a good working knowledge of UL ratings. However, one rating that gives many engineers trouble is UL 1604, which certifies electrical components for use in hazardous environments. We routinely field questions about UL 1604 and which products comply with it. Here are some answers.

    HE-V Relays  As solar farms and energy storage systems grow in scale, they increasingly require power Relays that can safely cut off high DC voltages. That’s where Panasonic's new HE-V Relay comes in. Designed specifically for alternative energy applications, this new 2 Form A power Relay provides oustanding capacity, reduced energy requirements, and can be used for a variety of appliactions.

    For all their promise, electric vehicles won’t really hit the roads in any great numbers until charging stations become more readily available. Fortunately, the creation of a charging infrastructure is underway based on three different types of charging stations. Here’s a look at these stations and why they need the right kind of DC relays to enable safe, effective electric vehicle charging:

    Measure Relay's Contact Resistance To Diagnose Failure Even the best Relays can fail at some point, but what causes them to fail? Conventional wisdom places the blame on worn out contacts. Every electromechanical Relay has a finite number of cycles it can endure before the contacts call it quits.

    Solid-State Relays In Test And Measurement Systems To keep pace with advances in the electronics industry, test and measurement systems increasingly require advanced solid-state Relays that combine low capacitance, low on-resistance, physical isolation, and high linearity. All these characteristics play an important role as data acquisition devices become faster and more precise. Here’s why:

    Pilot Duty Ratings A Relay can be assigned a Pilot Duty Rating when it is used for switching loads on another relay, or solenoid valve coils. It can be a direct current (DC) rating, or an alternating current (AC) rating, as shown in the table at the bottom of this post. The Pilot Duty Ratings are obtained after performing product qualification tests.  These tests are performed at the voltage and current values provided using the information in Table 1 below, with a 0.35 power factor.
