NK Technologies - Innovative Current Relay Can Measure Either AC or DC Loads Up to 400 A

November 29, 2018 - Innovative Current Relay Can Measure Either AC or DC Loads Up to 400 A.
The DS1-FD Current Relay features a large aperture for monitoring AC or DC loads up to 400 amps or higher. Just thread the conductor through the sensing window (aperture) and reconnect on the other side. The relay output is isolated from the monitored circuit and can switch up to two amps up to 125 VAC, or two amps to 30 VDC. The output contacts can reset to original condition on current fall or latch in the tripped condition. The trip point (where the output relay changes state) can be adjusted between 20 and 400 amps by adjusting two potentiometers. One provides a “coarse” adjustment; the second allows for fine tuning of the trip point. The maximum current is unlimited, so current higher than the highest adjustment point will keep the relay in the tripped condition.

• Trip point to 400 ADC or 388 AAC
• Can control an AC or DC circuit
• Not polarity sensitive with regard to the monitored circuit
• Externally powered, 24 VAC or DC (20–28V)
• Both NO contact for alarm and NC contact for disconnecting applications
• Factory calibrated, warranted to stay accurate for five years minimum
• Snap onto DIN rail or attach with screws to a panel for secure mounting

ALTECH CORP. Air Ventilation Enclosures

August 03, 2018 - AKIII Series - The Unique AKIII Enclosure with Patented Air Ventilation System
The patented Air Ventilation elements avoid condensate water while preserving the high protection class IP65. Occurring condensate is transported out of the enclosure immediately via air exchange. The continuous and high air exchange allows the interior air to mix constantly with the environmental air and transports the moisture outward. Even environments with nearly constant humidity and temperature possess air exchange, since the air on the interior of the enclosure warms due to the fittings. The individual components of the ventilation elements mainly consist of the rotating cover (rear side of box) and the 10µm filter element integrated on the inside of the box.

Advantages of Air ventilation elements:
• Prevention of condensate water while preserving the high protection class IP65
• High air exchange rate
• 100% pressure compensation
• Foreign object protection
• Maintenance-free

Altech - Ultra-Capacitor DC UPS

September 27, 2017 - Backup power systems are an integral part of installations as varied as data centers, wind turbine farms, telecommunications networks and industrial plant operations—all of which rely on the continuous availability of power.
Ultra-capacitors are best suited to these and other mission-critical applications that require seamless transition to backup power (UPS) over relatively short periods of time. In the event of a main power supply interruption, the energy stored in the ultra-capacitors is released. High energy batteries also have been developed for single use or rechargeable UPS applications, but they typically require minutes to discharge, not seconds. Unlike a battery, an ultra-capacitor doesn’t depend on a chemical reaction to charge or discharge so it's capable of fast response and the charge-discharge cycle life of a supercapacitor can be, typically, 15 years or more (depending on how many charges or discharges are involved).

NK Technologies - AGLD Ground Fault Sensors with Large LED Display Now UL Listed

September 27, 2017 - Protecting an electrical system from faults to earth can prevent accidental shocks to personnel and damage to equipment. The AGLD sensor provides a lower cost solution with a simple installation. Rather than combining a detector with a circuit interrupter, the sensor provides contacts to open or close when a fault is detected.
The large, one piece solid-core design allows for installation over wires feeding heavy loads. The output relay will change state at any point between 5 and 100 mA, or 80 and 950 mA. A delay can be set to allow down stream protection to activate before the sensor, keeping the main circuit protection hot and the equipment energized while the smaller faults are cleared. The large LED display shows the precise trip point and the extra delay clearly in any light condition.
• Electromechanical relay output provides both normally open and normally closed contacts and is compatible with most automation and control systems.
• Externally powered with a choice of fail safe or standard operation.
• A single turn potentiometer with the setpoint shown on the display makes adjusting the setpoint in the field easy.
• Large solid-core case with a large sensing window provides ample space for multiple conductors.
• Simple DIN rail mount for quick installation.
