Question 1

What power ranges do Wall Industries power supplies and converters cover?

Accepted Answer

DC/DC converters are available from 1/2 watt up to 1,500 watts, and AC/DC power supplies from 1 watt up to 3,600 watts. Mechanical formats include encapsulated, PCB through-hole, chassis mount, open frame, enclosed with or without fan, U-frame, DIN rail, wall plug-in and desktop.

Question 2

What is the difference between a modified-standard and a fully custom power supply?

Accepted Answer

A modified-standard unit starts from a proven catalog platform and changes only what your application requires — output voltage trim, connectors, cable harness, potting, coating, labelling or thermal derating. A fully custom design starts from your electrical, mechanical and compliance specification and is engineered from the ground up. Modified-standard shortens qualification time and cost; fully custom delivers exact form, fit and function.

Question 3

Which standards do your designs address?

Accepted Answer

Depending on the target market, our engineering team designs to requirements such as UL/IEC 60601-1 for medical equipment, MIL-STD-1275 for military vehicle power, MIL-STD-461 and CISPR/EN 55032 EMC limits, EN 50155 for rolling stock and DoE Level VI / EU CoC Tier 2 efficiency rules for external adapters.

Question 4

Can a power supply operate at extreme temperatures?

Accepted Answer

Yes. On request our engineers design converters and power supplies that operate from -55°C to +125°C, using component derating, conformal coating or potting, and conduction-cooled baseplate or chassis designs to remove heat without fans.

Question 5

How do I select the right power supply for my project?

Accepted Answer

Define the input source (AC mains range or DC bus), the number and value of outputs with worst-case load and transient current, required isolation, ambient temperature and cooling method, mechanical envelope and mounting, plus the safety and EMC standards your end product must certify to. If your specification is incomplete, our applications engineers help define the requirement before design work begins.
