CUI Introduces Low Power DIN Rail Dc-Dc Converter Family in a Slim Package04/07/2014

CUI Introduces Low Power DIN Rail Dc-Dc Converter Family in a Slim Package

CUI Inc today announced a compact DIN rail dc-dc converter line to ease installation in industrial environments.

The converter family is housed in a slim 76 x 31.5 x 25.8 mm (2.99 x 1.24 x 1.02 in) DIN-Rail package with all electrical connections easily accessible via screw terminals.

It has been designed for applications where the convenience of DIN rail mounting is required, such as industrial equipment, mobile equipment, and telecom base stations. The family’s 47 modules, across three series - PYB10-DIN, PYB15-DIN, and PYB20-DIN – have an output range of 10~20 W.

Available input ranges of 9~36 Vdc or 18~75 Vdc make the units ideally suited to battery-driven applications, where charging and discharging conditions require a wide input range. The devices’ -40° to +85°C operating temperature range also allows the series to work reliably in harsh environments. For applications where power consumption is a concern, the PYB series delivers efficiencies reaching 91%.

The PYB family is available in single output (3.3, 5, 12, 15, or 24 Vdc), dual output (±5, ±12, or ±15 Vdc), and in 15 and 20 W versions, triple output (3.3/±12, 3.3/±15, 5/±12, or 5/±15) models. Outputs are fully regulated to within ±0.5% for overall line input conditions and ±1.0% for all load conditions. Input to output isolation of 1,500 Vdc is provided across the range of models.

Single output 15 W and 20 W models offer an output trim that allows ±10% nominal output adjustment. All parts include a remote on/off feature. Protections include continuous short circuit, over current and over voltage. The PYB series meets CISPR22/EN55022 Class B standards with limited external components. An optional heat sink is also offered on most models for improved thermal performance.

The PYB10-DIN, PYB15-DIN, and PYB20-DIN Series are available now through distribution starting at $ 37.51 for 100 pieces. Please contact CUI for volume pricing.

Epson Electronics America, Inc. Press Release December 3, 2013


RX6110SA real-time clock module

-SAN JOSE, California December 3, 2013-

Epson Electronics America, Inc. ("EEA") today introduces the industry's lowest power real-time clock (RTC) module. With typical current consumption of just 130 nA Epson's RX6110SA current consumption level is 35% lower that that of the RX-8571SA, Epson's existing lowest-current RTC product.

Epson's RX6110SA enables the reduction of hazardous substances by allowing electronic device makers to replace batteries with supercapacitors. With a 0.33F supercapacitor, Epson's RX6110SA can operate for 16 weeks. Epson's RX6110SA achieves an operating current one half of leading competitors by employing special low-power circuit design techniques and Epson's unique low-leakage IC process technology. Compared to microcontroller implementations, Epson's RX6110SA can operate eight times longer.

The RX6110SA also includes a diode-less power-supply switching circuit which allows it to operate and charge from power supplies ranging from 5 V down to as low as 1.1 V. By operating at a lower voltage than competition, Epson's RX6110SA further extends battery life.

In addition to keeping time, real-time clocks are used to log power-loss events and save system state when power is lost. Epson's RX6110SA offers a rich feature set to support these needs, including a 32.768 kHz output, alarms and timers, and RAM. The RX6110SA supports both SPI-bus and I2C bus interfaces.

Main Specifications

Model number RX6110SA
External dimensions 10.1 x 7.4 x 3.2t (max.) mm
Timekeeper voltage range 1.1Vto 5.5 V
Operating temperature range -40°C to +85°C
Current consumption 130 nA (Typ.) / 250 nA (Max.) (3.0 V during operation)
Initial Frequency Deviation 5.0± 23.0 x 10-6 (Max.)
Interface SPI-bus and I2C-bus (selectable)
Functions Clock, calendar, alarm, long-term timers, frequency output, RAM, etc.
