Test conditions and notes5

1.All parameters are specified at normal input(F: 12Vdc, G: 24Vdc), rated load, 25℃ 70% RH ambient.
2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μf & 47μf capacitor.
3.Line regulation is measured from low line to high line at rated load.
4.Load regulation is measured from 10% to 100% rated load for MDD06.

FAQ

Can I use the MDD06G-12 for a 12V industrial I/O or relay interface board?

Yes, it is a fit for low-power industrial or automation circuits that need 12V and -12V constant-voltage output. The converter provides 6W total power with up to 0.25A per output from an 18-75VDC input range.

Is the MDD06G-12 suitable for embedded analog or instrumentation electronics that require ±12V rails?

It is appropriate for embedded analog and instrumentation sections that need dual 12V rails and stay within the 6W power limit. The 0.25A per output rating makes it better suited to low-power boards than heavier 12V loads.

Would this converter work in medical or lab equipment that runs from a higher-voltage DC source?

Yes, this medical grade model is intended for equipment operating from the stated 18-75VDC input range and needing 12V and -12V output. Its compact 31.8 × 20.3 × 12.2 mm size also helps in space-constrained assemblies.

Can the MDD06G-12 be used in compact automation modules where weight matters?

It can, since the unit weighs 0.017 kg and has a small footprint of 31.8 × 20.3 × 12.2 mm. Those specs make it practical for compact embedded and automation electronics that require ±12V power.

How does the MDD06G-12 compare with the MDD06G-05 and MDD06G-15?

All three are 6W medical grade DC/DC converters with the same 18-75VDC input range. The difference is output: the MDD06G-05 is ±5V at up to 0.6A, the MDD06G-12 is ±12V at up to 0.25A, and the MDD06G-15 is ±15V at up to 0.2A per output.

Is the MDD06G-12 designed for indoor or outdoor use?

The datasheet details an operating temperature range of -40°C to +90°C, with output derating at higher ambient temperatures per the derating curve. No IP rating is listed in the provided specs, so the product data does not define it as outdoor rated.
