Programmable Switching Power Supplies
PeakTech Prüf- und Messtechnik GmbH
In addition to presets for current and voltage values, time programs with intervals and the number of runs can also be created directly on the device or using the included PC software. For operation with a PC, the switching power supply is equipped with a USB and RS-485 interface. A PC connected to the RS-485 interface enables the control of up to 32 power supplies. A USB interface on the back of the device connects to a Windows PC. The intelligent fan control adjusts the speed of rotation to the respective temperature and output power. The output voltage and current limit can also be set in the open circuit without a connected load. Due to its high reliability and the programming functions, this power supply series is ideal for professional users from industry, control and regulation technology or the electronics laboratory.

Enhanced Serial Interface Module for the Multiprotocol Excalibur 4000 Family of Carrier Boards
M4KSerialPlus
The M4KSerialPlus is an enhanced serial interface module for the multiprotocol Excalibur 4000 family of carrier boards, that includes several advanced features such as a high baud rate and high throughput. This module supports up to four independent channels of serial communications, each of which can be selected as RS-485, RS-422 or RS-232. The module operates independently of the host computer, reducing the need for host intervention.The M4KSerialPlus module is based on the Exar XR16M570 Universal Asynchronous Receiver/Transmitter (UART). The device is compatible to industry standard 16550 UARTs. Each of the M4KSerialPlus’s four channels contains a transmit FIFO capable of holding up to 16384 bytes and a receive FIFO capable of holding either 16384 receive bytes or 5460 bytes with a 32-bit Time Tag associated with each byte. These large buffers allow application code to transfer large quantities of data with a single non-blocking subroutine call. The 32-bit Time Tag on receive channels is very useful for synchronizing serial data with data from other modules on the 4000 board or on other interface boards. Each channel has a programmable baud rate of up to 10 Mbps and can be configured as RS-232, RS-422 or RS-485.The M4KSerialPlus module is supplied with C drivers, including source code.

RS232 / RS485 / RS422 / Serial To Multi-Drop Fiber Optic Converters
Our advanced, rugged, industrial-grade, RS232 / RS485 / RS422 serial to multi-drop fiber optic converters are designed to cover large areas. These converters support up to 255 fiber nodes, and each fiber node can extend the RS232 / RS422 / RS485's distance to 3 miles (5km) for multi-mode converters and cables, or 25 miles (40km) for single-mode converters and cables. Depending on the site situation, these multi-drop fiber optic converters can be configured as a daisy-chain or a self-healing redundant ring fiber network. When configured as a ring fiber network, the built-in self-healing feature allows the data to be transmitted clockwise or counterclockwise; therefore, failure of any individual converter will not affect other devices located on the same fiber ring, making the entire data network more robust and reliable. These multi-drop fiber optic converters have been designed for harsh industrial environments and withstand a wide temperature of -40°F to 185°F (-40°C to 85°C), and they come with the options of multi-mode and single-mode, and ST, SC, and FC connectors.
