1. What input voltage does the KH30F support?

The KH30F accepts a universal single-phase input range of 85–264Vac at 45–440Hz. It can also operate from an 88–370Vdc input. Derating applies when the DC input voltage is below 110Vdc.

2. What output models are available?

The KH30F is available in three output configurations: 5Vdc at 5A and 25W, 12Vdc at 2.3A and 27.6W, or 24Vdc at 1.3A and 31.2W.

3. Can the KH30F output voltage be adjusted?

Yes. The 5Vdc model adjusts from 4.5Vdc to 5.5Vdc, the 12Vdc model from 10.8Vdc to 13.2Vdc, and the 24Vdc model from 22.5Vdc to 28.5Vdc.

4. Does the KH30F require a cooling fan?

No. The KH30F uses natural convection cooling and does not require an integrated fan. It operates from -20°C to +70°C, subject to the mounting and output derating requirements in the datasheet.

5. What is the difference between the KHEA30F and KHNA30F?

Both versions provide the same core electrical performance. The KHEA30F uses Euro-style input and output terminals, while the KHNA30F uses barrier-block terminals. A conformal-coating option is also available for additional environmental protection.

KH30F Cosel

The KH30F Cosel 30W DIN rail power supply provides regulated DC power for PLCs, sensors, instrumentation, control systems and compact industrial equipment. Output options include 5Vdc at 5A, 12Vdc at 2.3A and 24Vdc at 1.3A, with adjustable output ranges for matching different load requirements. Built-in overcurrent, overvoltage and inrush-current protection help safeguard the power supply and connected equipment. The KH30F operates from -20°C to +70°C, subject to derating, and uses natural convection cooling. Euro-style and barrier-block terminal versions allow engineers to select the preferred connection method.

KH30F Cosel

The Cosel KHEA/KHNA30F is a compact 30W DIN rail power supply designed for industrial automation, instrumentation and control-panel applications. It accepts a universal 85–264Vac or 88–370Vdc input and is available with regulated 5Vdc, 12Vdc and 24Vdc outputs.

Measuring only 22.5mm wide, the KH30F supports space-efficient installation on a standard 35mm DIN rail. Natural convection cooling, efficiency of up to 89.5% and low no-load power consumption support reliable fanless operation.
