Screw Type & Encapsulated Bridge Stacks for Power Electronics

Screw type & Encapsulated bridge rectifiers

This section shows to families of SCR & Diode stacks, in one side we have power stacks mounted with screw type devices , available diodes and thyristors, allows the construction of cheap and robust rectifiers, and in the other side power stacks mounted with multichip modules, habitually 1~ and 3~ bridge rectifiers, DIN rail series available.

Power stacks with screw type devices:

RR Series

Standardized blocks “sink + diode” that allow the construction of circuits for rectification. Available three different heatsinks to optimize space, our profiles RG10090, RG11205 and RG11087.

RA Series

Power stacks with screw type semiconductors for medium power rectifying applications. This power stacks can be cooled by air, water or oil. This series is indicated for reliable rectifying systems at best cost/amp ratio.

Stacks with encapsulated bridge rectifiers:

CC Series

Power stacks mounted with multichip modules, habitually 1~ and 3~ bridge rectifiers. Habitually used for CC power supply for any industrial application. Compact design, ready to use and opcional varistor included for industrial applications.

CF Series

Compact designed bridge rectifiers for DIN rail mounting, including protection by input/output varistor and input/out fuse. Specially appropriate for the CC supplying in cabinets for elevators and cabinets with a lot of relays.

SSR Firing Boards for Power Electronics

Solid State Relay Firing Boards

Zero-cross, instantaneous and configurable firing boards, designed to support voltages from 25V until 1200V, all our serie triggers 2 thyristors in antiparallel (W1C), which allows to obtain great advantages in the connection of loads. Furthermore, every board has a state control LED indiction.

Its devices are modular, using two or three modules/cards, it is possible to make three-phase applications (W3.2C and W3C).

Vrms [V]	Zero-Crossing	Instantaneous
25	SC010L
420	SC010	SC011

Vrms [V]	Zero-Crossing	Instantaneous
500	SC016
720	SC018	SC019
960	SC024
1200	SC030	SC031

Features SSR Firing Boards:

Configurable

It is intended to be used in applications where high reliability is needed. This card is configurable to trigger SCR’s with pulse trains synchronized with mains voltage, or in permanent mode. It can be configured to start at zero crossing or random phase.

Control signal can be a logic level referred to card reference (high input impedance) or floating optocoupled input (low input impedance). Built-in power supply is feed directly from the mains, either 230 VAC or 400 VAC, 50/60 Hz.

Zero-Cross

The main zero-crossing advantage is decrease the surge current through the load during the first conduction cycle and helps reduce the level of conducted emissions placed on the AC mains. That occurs because the switching of the relay from a non-conducting to a conducting state occurs when the AC mains voltage reaches the zero-crossing point of the sine-wave.

Instantaneous

Instantaneous solid-state relays turn on immediately after the application of the control signal. The output of the relay immediately begins to conduct load current as opposite to a zero-crossing relay.

High Efficiency Heatsinks for Power Electronics

We offer to you our own manufactured and exclusive designed range of high efficiency heatsinks made of aluminium stacked and pressed single fins with our exclusive mounting process to achieve a great performance and outstanding structural integrity.

Nowadays the dissipation requirements in reduced spaces are growing, thanks to our technology you can improve thermal dissipation performance of your power equipment without compromising costs and dimensions.

These heatsinks are widely used in traction applications, windmills and high power supply designs. Available in two-side cooling with RG40080 series, even three-side cooling with our RG42080L and RG42120L range or just the standard one-side cooling at different heights with RG42080N and RG42120N.

We also offer customized designs for any requirement requested from our customers putting all our know-how and capabilities along with our high-efficiency heatsink innovative and versatile constructive technology. Also we have available a combi serie combining high efficiency heatsink with forced ventilation, see more information in Combi Thermal Management.
