Overview
The DMTT-300 is a 300VA laminated power transformer designed for chassis mounting. It features a dual primary winding supporting multiple input voltages: 200V, 220V, 240V, 400V, 420V, 440V, 460V, and 480V. The secondary configuration provides three outputs: two parallel windings rated at 12V/25A and one series winding rated at 24V/12.5A. The unit measures 104.80mm in length, 128.10mm in width, and has a maximum installation height of 98.20mm. It weighs 4.5 kg and offers 4000Vrms isolation voltage.
Feature Summary
- Dual primary winding design accommodates a wide range of standard AC input voltages for global compatibility.
- Three secondary output configurations provide flexible voltage and current options via parallel or series connections.
- Laminated core construction ensures stable performance for industrial control applications.
Applications
- Industrial machine tool control systems
- General industrial equipment power distribution
- Control panel voltage transformation
Procurement Notes
Verify the specific primary voltage requirement against the available ratings (200V to 480V) before ordering. Confirm that the chassis mounting dimensions and terminal block style align with the enclosure design. Ensure the secondary load does not exceed the specified parallel or series current limits. Check RoHS compliance status if required by project specifications.
Selection Notes
Select this model when a 300VA capacity is required for chassis-mounted installations. Choose based on the need for multiple secondary outputs (12V and 24V) from a single unit. Consider the physical dimensions (104.80mm x 128.10mm) for space constraints. Verify that the operating frequency matches the system requirements of 50Hz or 60Hz.
Part Context
The DMTT-300 belongs to the DMTT series of laminated power transformers manufactured by Signal Transformer. This series is engineered for robust industrial environments, offering high isolation and reliable voltage conversion. The component serves as a critical interface between main power sources and sensitive control circuits in heavy-duty machinery.
Replacement Considerations
Consult official Signal Transformer documentation for direct cross-references. No public substitute part numbers are confirmed in the provided data.
