How do I start selecting a Cincon converter?

Fix the input bus and the output voltage, size the power with margin, then confirm the input range, the isolation and the package. Those decisions narrow the selection quickly.

Which input range do I need?

Choose a 2:1 range for a modestly varying bus and a 4:1 range for a widely varying source such as a battery or a railway supply. The Cincon EC series covers both, so match the range to how much the input moves. Our FAE team can help choose the range.

Do I need an isolated output?

Choose an isolated output where the board must be separated from the bus, where a ground loop would corrupt a measurement or where a standard requires it. The Cincon EC modules provide about 1500 VDC isolation, which separates the input and the output. Our FAE team can help with the isolation.

Are the modules genuine and documented?

Every Cincon module BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Mainstream models are held in regional warehouses. Click a model for stock status, or request a quote for current lead time.

How do I start selecting an AC-DC supply?

Add the load and margin, choose the output voltage, then confirm the input range, the cooling and the mechanical form and the safety and the EMC approvals. Those decisions narrow the selection quickly.

What power do I need?

Add the load of every rail, add margin for the start-up and the lifetime, and choose the next standard wattage up. The Cincon CFM series spans 4 W to several hundred watts, so most designs have a fit. Our FAE team can help size the supply.

Do I need an external EMI filter?

The Cincon CFM series meets the EN55032 Class B emission on its own, so a separate filter is not always needed. Confirm the emissions with the real load and the enclosure, and add a filter only where the layout or the load demands it. Read the power design notes for the details.

Are the supplies genuine and documented?

Every Cincon supply BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Mainstream models are held in regional warehouses. Click a model for stock status, or request a quote for current lead time.

How do I start selecting a railway converter?

Fix the rail input range and the output, confirm the EN50155 class and the isolation, then choose the mounting and the thermal path from the cabinet. Those decisions narrow the selection quickly.

Which standards must the converter meet?

A railway converter meets the EN50155 for the rolling stock, the EN50121-3-2 for the EMC and the EN45545-2 for the fire behavior, with the 3000 VAC isolation. Confirm the standard and the class against the project, because the requirement differs between the applications. Our FAE team can confirm the compliance.

How do I handle the wide input?

Choose a module with an ultra-wide input range, such as the 10-160 V of the Cincon EC7AW18 and EC7BW18 series, and confirm the ride-through and the protection against the EN50155 class, so the output survives the supply variations. Read the power design notes for the details.

Why is derating important?

A converter or a supply delivers less than its full rating at a higher ambient, so the derating curve sets the real available power. Keep thermal margin so the part runs cool, which lengthens its life and lowers the failure rate. Read the notes for the derating rules.

How do I lay out a power design?

Keep the input capacitor close, keep the switching loop small, reserve the creepage for the isolation and keep the noisy nodes away from the sensitive load. Use a ground plane and follow the datasheet and the application circuit. Our FAE team can review the layout.

How do I meet the EMC and safety limits?

The Cincon CFM series meets the EN55032 Class B emission on its own, and a DC-DC module needs the recommended pi input filter. Confirm the emissions and the leakage on the bench with the real load and the enclosure. Our FAE team can review the EMC design.

Are the parts genuine and documented?

Every Cincon part BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Mainstream models are held in regional warehouses. Click a model for stock status, or request a quote for current lead time.

What is the standout feature of the Cincon range?

The standout feature is the breadth of the power range, from a 3 W board-mount DC-DC module to a 500 W open-frame supply and a railway turnkey module, so a designer can source the whole power chain from one supplier with a competitive cost. The main design care points are the derating and the railway compliance.

How do the DC-DC converters perform?

In practice the Cincon EC modules give a clean isolated rail across the load with a wide input range, and the shielded 2x1 inch case and the low no-load current suit a continuous design. On the bench the ripple and the regulation held across the range. Confirm the input range and the isolation.

How do the supplies and railway parts perform?

The Cincon CFM open-frame supplies meet the Class B emissions on their own and derate as the datasheet shows, and the railway modules accept the ultra-wide input and meet the EN50155 compliance with a baseplate cooling. Our FAE team can review the design.

Can I get samples to evaluate?

Yes. We provide samples of the Cincon converters and supplies for your own efficiency, thermal and EMC testing, with documentation included and FAE support during bring-up. Request a sample and we will confirm stock and lead time.
