AC line adds two models in 4U

Asterion AC power sources have added Asterion 4503 that delivers AC and DC output power up to 4,500 VA or 4,500 W, and Asterion 6003 that delivered up to 6,000 VA or 6,000 W. Both intelligent, modular units have an intuitive touchscreen interface, come in a 4U chassis, and can supply single- or three-phase output power. Asterion offers AC and DC output voltage ranges up to 400 Vac and 500 Vdc, while load and line regulation are ±0.025% and ±0.015%, respectively.

They also feature iX2 current-doubling technology that increases available output current up to two times the rated output current as output voltage decreases from maximum value to one half maximum value. This allows Asterion to maintain maximum power through the widest range of voltages.

Asterion comes with standard LXI LAN, USB, and RS-232 interfaces. An optional GPIB interface is also available. Intuitive Virtual Panels control GUI software comes bundled with the instrument for easy remote control from a computer. Included drivers let users quickly integrate the unit into ATE systems.

Asterion also features auto-paralleling and clock/lock. With autoparalleling, users can combine up to six units to achieve 36 kVA of output power. One unit becomes the master, while the rest serve as auxiliary units. Clock/lock lets users easily configure multi-phase systems, such as split-phase, three-phase, or even higher phase count systems.

Genesys 1U full-rack, 1.7 kW AC/DC programmable power supplies provides 10 models, ranging from 10V-170A to 600V-2.8A.

Built into a lightweight 1U high, 19-in. (483-mm) wide rack-mountable chassis, Genesys offers five embedded front-panel setup menus that include digital communication, protective functions, operating configuration, system configuration and system triggering. These menus offer user-selectable functions including internal resistance simulation and slew-rate control of output voltage/current, and have the capability to generate, store, recall and activate up to four on-board arbitrary waveform profiles.

All models can operate in constant-current (CC), constant-voltage (CV) and constant-power (CP) limit. and have conversion efficiencies up to 90%. Operation from a wide-range single-phase AC input (85 VAC to 265 VAC) is standard along with built-in power factor correction (0.99 typical) and cooling fan speed control (for reduced audible noise and extended life).

Standard safety features include user-selectable safe-start/auto restart and last setting memory, along with other built-in protective functions (OVP, UVL, UVP, fold-CV, fold-CC, OCL and OTP) and up to four units can be connected in parallel with an auto-configuring advanced parallel system that provides dynamic response and output voltage ripple/noise characteristics comparable with that of a single unit.

All model functions can be programmed locally via the menu-driven front panel display, or remotely using software instrument drivers with any one of the three built-in standard digital interfaces (LAN (LXI 1.5), USB (2.0) and RS-232/RS-485). Other programming interfaces include the built-in standard isolated analog program/monitor/control interface and the optional IEEE (IEEE 488.2) digital interface.

Easy, flexible mounting; no point-to-point wiring

K-System Power Rail ensures easy, flexible mounting and power distribution without labor-intensive, point-to-point wiring. It ensures the reliable supply of power to modules, and since no separate wiring is required, it also reduces installation costs. K-System transmits a collective error messages in the event of faults, which are detected by the interface module, and outputted via the volt-free contact of the power feed module. Power is supplied via a power feed module that provides 24 V DC (maximum 4 A) to as many as 80 devices.

Couplers provide short-circuit protection

TG200 Trunkguard fieldbus device couplers enable implementation of fieldbuses by connecting multiple devices to a main trunk. They're available with four, eight or 10 fieldbus spurs, and can handle four to 20 fieldbus devices in Foundation fieldbus and Profibus PA networks. TG200 uses a fold-back technique to disconnect a shorted instrument from the fieldbus segment, preventing complete segment failure. This fold-back method uses a logic circuit on each spur, which detects a short in an instrument, disconnects that spur from the segment, and illuminates an LED that can be seen by maintenance personnel.

TG200 can be DIN-rail mounted or enclosed in IP66-rated, glass-reinforced polyester (GRP) or stainless steel enclosures. Up to 32 fieldbus devices can be accommodated by one segment. It also has ATEX/FM approvals for use in Zone 2 and Div 2 hazardous areas. Other models are available for other hazardous area classifications or other protection concepts.

TG200 also has a patented Automatic Segment Termination feature that eliminates problems caused by over- or under-termination by automatically activating when the device coupler determines it's the last fieldbus junction device in the segment. If a TG200 is disconnected from a segment accidentally or for maintenance, Automatic Segment Termination also detects the change, and terminates the segment at the proper coupler.
