Schurter is expanding its successful FMER series of high-current filters with a model for high power. The entire series is now available without grounding capacitors for safety-related applications.

Photovoltaic panels with increasing surface areas are being installed, and as a result ever more powerful inverters are required. To address this trend, SCHURTER is expanding the current ratings of its DC filters to 2300 A for higher power. For reasons of safety, filters are sometimes requested without grounding capacitors, which prevents any leakage current to ground. Thus, Sschurter is also offering this entire series without Y capacitors.

Modern solar inverters with MPP (maximum power point) trackers generate interference in both directions: on the AC grid side and the DC panel side. On the AC side, it is usual to insert an AC filter such as the SCHURTER FMAC or FMBC, but until now few provisions have been made for the DC side. EMC standards EN 61000-6-3 and EN 55014-1, however, also limit the level of interference on non grid-connected conductors such as those going to a solar panel. A remedy can be provided by DC filters installed on the DC side of the solar inverter.

Large solar inverters are generally housed in cabinets that must have active cooling. The Schurter FMER series features high temperature resistance, which reduces the necessary cooling energy and makes a significant contribution to higher energy efficiency for the entire system.

FMER family filters have UL approvals for ambient temperatures of +55°C and +75°C as well as for rated voltages of 600 VDC and 1000 VDC. They are exceptionally well suited for rated currents from 25 A to 2300 A at an ambient of 55°C and for voltages up to 1200 VDC.

FMER SOL DC filters come standard with screw terminals up to 150 A, and with copper bars starting at 250 A. Other connection types (stranded wire or copper bar for current levels less than 250 A or bus bar terminals) are available on request.  In addition, small modifications to the switching or the housing are also possible on request.

For optimal matching to the inverter, Schurter offers its own EMC measurement service that makes it possible to find the most cost-effective filter solution.

Technical features:
– Rated voltage 1200 VDC
– Rated current 25 A to 2300 A
– Connections: screw terminals 25 - 150 A; copper bars 250 - 2300 A
– cURus approval: 600 VDC 25 - 150 A, 1000 VDC 250 - 2300 A

This new model with a patented ceramic actuator face expands SCHURTER’s MSM family of metal pushbutton switches with rugged background illumination over the full actuator surface. The material is resistant against scratches, abrasion and impact as well as chemicals and makes the unit well suited for many applications in medical technology and industry. 

The new MSM CS metal pushbutton switch from SCHURTER is equipped with an actuator made of rugged ceramic. Ceramic is being employed for the first time in an operating switch and is patented by SCHURTER for this application. The material is resistant against scratches, abrasion and impact as well as chemicals; it can also be labeled and is translucent. Equipped with these versatile features, the MSM CS pushbutton switch opens up completely new possibilities in the construction of medical equipment and in industry.

If the switch is not illuminated, the actuator surface is white. Standard or customer-specific lettering is in black and embedded directly into the ceramic material.

In the illuminated versions of the switch, the actuator face fully illuminates across the entire surface, and lettering and symbols can also be applied. Positive lettering is done in black; for inverse lettering, the label text appears in the selected illumination color. Because of the way they are made, the labels are scratch-proof and stand up to common cleaning agents.

Thanks to a small, low-profile front mounting of 1.7 mm, the IP69K protection class and high level of impact resistance, the switch is extremely robust and protected against vandalism. The MSM CS is available for mounting diameters of 19 and 22 mm. Various contact types cover a range for allowable switching voltages from 30 VDC to 250 VAC; allowable switching currents range from 0.1 to 10 A. For fast wiring, the MSM CS provides blade terminals. Wires are connected to the microswitch element, which is subsequently snapped onto the previously screwed-in switch housing.
