Schaefer Intros High Density 3000W DC/AC Inverter
Ashland, MA — Schaefer has intro- duced the PRP-3000 Series of highly efficient, pure sine wave inverters that provide up to 3000VA of power. The new inverters are available in versions that meet industrial (EN60950) or rail (EN50155) standards. Standard input voltages of
24VDC, 36VDC, 48VDC, 72VDC, and 110VDC are inverted to adjustable 120VAC or 230VAC outputs that are regulated to 4 percent or better. Units can be configured for three-phase syn- chronization. All models in the series have
overload protection and an LED indi- cator for output OK or alarm condi- tions. A wide operating temperature of -25 to +70°C allows for installations in extreme conditions and meets EN50155 Class 3. Remote inhibit and remote off
are standard in the design. Units are highly efficient, with ratings ranging from 88 percent to 91 percent. Emissions to EN61000-6-4 and
Bliley Intros First in New OCXO Series
Erie, PA — New from Bliley Tech - nologies, Inc. is the Apollo OCXO series oscillator with exceptional phase-noise performance in a low pro- file, 1.0 x 1.0 x 0.460-in. (25.4 x 25.4 x 11.7mm) package. According to the company, the new oscillator provides excellent frequency versus tempera- ture stability, design flexibility with
EN60121-3-2 meets both industrial and rail standards and minimizes
interference to other sensitive equip- ment. Status and programming is con-
trolled through the RS-232 interface. The company’s full family of
pure sine wave inverters also includes other standalone modules starting at 250W of power, and high- er power rack designs up to 5000W that include a UPS. Modifications to standard units are available. In addi- tion, the company can design and
manufacture fully custom solutions. Contact: Schaefer, Inc., 200

New oscillator series.
customizable frequencies from 30 to 130MHz, solutions for meeting com- pact design challenges, and RoHS- compliant versions as needed. The new OCXO provides ultra-
low phase noise performance with excellent temperature stability in a miniature package. The series is designed for demanding applications requiring superior noise performance out to a 100kHz offset, and is well suit- ed for use in satellite, medical imaging equipment, telecommunications, up/ - down frequency converters, trans- ceivers, test equipment, phase-locked microwave sources and radar systems. Bliley is one of the few U.S.
companies that still performs onsite quartz crystal manufacturing for custom oscillator designs, such as the Apollo OCXOs. The company’s Apollo series oscillators are manufactured in the USA at the company’s Erie facility. Option “D” phase noise units
are available for quick turn delivery. Contact: Bliley Technologies,
