Advanced Energy Industries, Inc. has announced the launch of the PV Powered (PVP) HE String inverter line, suited for North American residential and small-commercial rooftop installations. The new PVP HE String line is one of the first inverters to offer standard ZigBee wireless monitoring.

ZigBee based wireless monitoring allows the new PVP HE String inverters to communicate with an optional AE wireless gateway. The design and wireless features eliminate the need for inverter modifications in the field as well as complex cable configuration from the inverter. Integrating ZigBee monitoring also allows compatibility with other ZigBee enabled Smart Grid communication devices such as smart appliances, utility Smart Meters or home area network (HAN) controllers.

The PVP HE String line offers power ranges from 3.8 to 7 kW and will be available in Q2 2012. AE's new line of string inverters are covered by a standard 10-year warranty with optional 15- and 20-year warranties.

Thermistor strings

Aquatemp Global has introduced thermistor strings to monitor and record in real-time, water temperatures in up to two-mile long multi-point polyethylene cables for bottom-laying or vertical suspensions. Sensors, attached at customer-specific points, are buried in the interstices of the multi-conductor cables, making them virtually damage-proof. They can be laid into lakes and rivers, bays and oceans.

Additional sensors can be combined in the thermistor strings, including sensors to detect chemicals, motion and radiation. Underwater cables run to the shoreline, then direct-buried or hung in air on poles to the control room or recording station computers. The cables and housings are made from polyethylene which has total immunity to water and also to persistence of radiation. Repairs, splices and extensions are made simply by a portable injection molding kit that Aquatemp has developed for on-site work.

The horns are designed with three alarm stages, with synchronized outputs up to 116dB(A) and a choice of 45 international tones. The 5 and 10 Joule strobe units have a choice of six lens colors and are powered by user-replaceable plug in Xenon tube modules. The PA loudspeaker versions have 15 Watt RMS outputs, generating sound levels of up to 118dB(A) with an operating frequency range of 400 to 8000Hz. The E2xCS combined 110dB(A) horn and 5 Joule Xenon strobe unit provides efficient and cost-effective audio-visual signaling in a single product.

Alarm with beacon

E2S announces a new safe sounder and strobe family. The IS-minialarm is a 100dB(A) sounder, the IS-minialite beacon uses an array of six high intensity LEDs and the minialert is a combined unit with the beacon mounted in the center of the horn. All versions are of cylindrical construction measuring 88 mm in diameter and are ATEX, IECEx, FM and GOST R approved.

The minialarm sounder has 49 user-selectable three-stage alarm tone configurations and a 4 MHz clock. The beacon uses amber, red, blue or green LEDs to produce a 1 HZ or 2 HZ flashing warning signal.
