The 5MPA series ac film capacitors handle from normal line frequency currents to 83.2 A_RMS from 2 kHz to resonant frequency. They offer a high voltage rating of 530 V ac and a dissipation factor of 0.1%. Flat copper terminations enable wide frequency response and low electrical and thermal impedance. Capacitors with values up to 10 µF come with brass bolt terminations. Devices at values up to 100 µF come with a “bridge and bolt” design. Operating up to 85°C, the capacitors perform over the current-handling spectrum from 50 Hz to 20 kHz superimposed feedback. Units are wrapped with flame-retardant insulating sleeves and end-filled with a flame-retardant potting compound. Optional molded mounting brackets are available for higher-value capacitors. Available now, the 5MPA capacitors cost between $6 and $30 each, depending on power requirements and quantity ordered.

Now available from Farnell stock, The Texas Instruments (TI) ADS5400 is a 12-bit, 1GSPS analogue-to-digital converter (ADC) that operates from both a 5V supply and 3.3V supply, while providing LVDS-compatible digital outputs.

The analogue input buffer isolates the internal switching of the track and hold from disturbing the signal source. The simple 3-stage pipeline provides extremely low latency for time critical applications. Designed for the conversion of signals up to 2GHz of input frequency at 1GSPS, the ADS5400 has outstanding low noise performance and spurious-free dynamic range over a large input frequency range.

The ADS5400 is available in a TQFP-100 PowerPAD package. The combination of the PowerPAD package and moderate power consumption of the ADS5400 allows for operation without an external heatsink. The ADS5400 is specified over the full industrial temperature range (-40C to 85C), says the company.

A new 1050W model has been introduced by Emerson Network Power, expanding its line of bulk front end AC/DC power supplies that meet the Climate Savers Computing gold standard for EFFICIENCY. The new DS1050-3 has a power density of 19W per cubic inch and can achieve a high typical conversion efficiency of 92 percent at 50 percent full load.

The company’s front-end power supply line-up offers ratings up to 3kW and feature industry-leading efficiency and density in standard 1U, 2U or 3U form factors for applications using distributed power architectures, such as computing, storage, networking, datacom, and test and measurement systems.

The DS1050-3 generates a main payload output of 12VDC and an auxiliary output of 3.3VDC, or 5VDC as an option, for powering standby circuitry. It features a wide 90 to 264VAC input voltage range and employs active power factor correction to minimize input harmonic current distortion and ensure compliance with the international EN61000-3-2 standard, with a power factor of 0.99 typical. To simplify incorporating the new power supply in equipment designs, it accepts the widely available IEC C14 ac input power connector.

Digitally programmable, the Emerson Network Power DS1050-3 is equipped with an I2C interface available with industry-standard PMBus communications protocol. It also contains a memory device (EEPROM) that is pre-programmed with data about the unit, including its type, serial number and date of manufacture, to facilitate replacement in the field.

With active single-wire current sharing that operates from 10 percent to 100 percent of load, multiple supplies can be easily paralleled for very high-current applications. The DS1050-3 is hot pluggable, has no minimum load requirement, and incorporates low-loss internal ORing Field Effect Transistors (FETs) on its main 12V output, for fault-tolerant and N+1 redundant applications.

The DS1050-3 incorporates fan cooling with automatic speed control and has an ambient operating temperature range of -10C to +50C, with 50 percent derating at +70C. It is comprehensively protected against overload and overvoltage conditions and delivers a demonstrated mean time between failures (MTBF) of more than 500,000 hours. The power supply meets the rigorous EN55022-B and FCC part 15 Class B conducted and radiated emissions standards, and holds a full complement of international safety certifications: UL/cUL, NEMKO+ CB, EN60950, CE Mark and China CCC, says the company.

Proprietary thermal management technology, utilized in Crydom’s new SeriesOne DR line offers 6A and 12A single and 6A dual-channel output ratings in compact 11mm and 18mm wide DIN-Rail mounted solid-state relays (SSRs).

The SeriesOne DR family SSRs are intended for use in heating, lighting and motion-control applications where DIN-Rail mounting is preferred and higher output power ratings are required. Featuring a proprietary thermal management design with no exposed hot metal surfaces for safety, the SeriesOne DR family includes AC output ratings at 40C ambient for single-channel models of either 6A or 12A, and dual AC output models with 6A per channel, each rated at either 12 to 280VAC or 24 to 600VAC. DC output model ratings at 40C ambient include single-channel versions rated at either 6A or 12A and 1 to 60VDC or 1 to 100VDC.

The SeriesOne DR features 4 to 32VDC, 90 to 140VAC, 208 to 265VAC or 18 to 36VAC inputs and includes an LED input status indicator. The 6A single-channel versions are 11mm wide while the 12A single-channel and 6A dual-channel SSRs each measure 18mm, all mounting on the industry standard 35mm DIN-Rail.

AC output versions offer 3.75kV all solid-state optical isolation with SCR outputs and are available in either zero voltage turn-on for resistive load applications, or random turn-on for inductive load applications. DC outputs offer 2.5kV all solid-state optical isolation with FET output for either resistive or inductive load applications. SeriesOne DR SSRs are RoHS and China RoHS compliant, CE certified, UL and cUL recognized including both general-purpose and motor-controller ratings, says the company.
