HEATING TECHNOLOGY EW MSR

Product catalog summary

Overview: The document provides technical specifications and operational guidelines for Schniewindt's heating technology products, focusing on power control units and thyristor control units. It highlights the features, configurations, and safety measures integrated into these systems.

Specifications:

Compact power control unit using TRIACS for up to 8 kW ohmic load.
3-phase economy circuit design, allowing delta or star wiring without a neutral conductor.
Temperature monitoring of power semiconductors using PTC resistors.
Galvanic isolation between control and load circuits via optical couplers.
Integrated load relay for overtemperature shutdown and semiconductor fuses.
Passive cooling with heat sinks capable of horizontal or vertical mounting.

Thyristor Control Unit Features:

Reversible input signals: 0 to 10V, 2 to 10V, 0 to 20mA, 4 to 20mA, and logic signals 5 to 24V.
PWM timebase adjustable from 1 to 127 seconds.
Protective shutdown for overtemperature conditions in thyristor controller and switchgear cabinet.
Three changeover contacts and status LEDs for operational readiness and fault indication.
Configuration via DIP switches, with optional fan control for specific temperature thresholds.

Safety and Monitoring:

Fault detection for clipper contact, overtemperature of thyristor power unit, and switchgear cabinet.
Visual fault indication through red status LED, with automatic resumption of normal operation once faults are cleared.

Certifications and Approvals:

Certified by RW TÜV, CSA, ANSI, UL, DEKRA, DNV GL, EAC, RTN/KTN, and others.
Compliance with standards such as DIN 2303GSI SLV, DIN EN 15085-2GSI SLV, 2014/68/EU, DGRL HP0, ATEX, and IECEx.

Company Information:

Schniewindt GmbH & Co. KG, located in Neuenrade, Germany, with a branch in Shanghai, China.
Contact details provided for both locations.
