Connector For MeanWell Power Supply

I got this MeanWell power supply on Ebay. It's 48V at 3.34 Amps. Should be enough for an analog 50W at 4 Ohm power amp. My hope is to design an amp for the novice builder and eliminate the need to do any Mains wiring. 48 Volts can still sting a little, but not near as much as 220VAC.

Anyway, there is one small problem. This supply comes with a DIN R7B connector. It looks similar to the DIN connectors that have been around for ages, but it has four pins in a 2x2 pattern unlike a semicircle pattern like the ones I used to seeing. Some of these supplys come with the same plug that is used on effects pedals. Imagine what would happen if you plugged a 48V supply into your favorite stompbox.

Does anyone know where I can get a female DN R7B that can be installed on the outside of a box ? One vendor of these supplys will sell a cable mount connector if you purchase the supply form his company.

Thanks for the info. Shipping and duties are almost $50 USD pushing the cost to over $10 each on quantity 5.

I googled that part number (KCN-KPJX-PM-4S) and got lots of hits including Mouser and Digikey, also Jameco.
