Details: This DC power supply is adjustavle from 0V-30V and 0A-10A. The 4-digit LED Display permits power supply accuracy to 0.01 V and 0.001A. This DC switching power supply is lightweight, small in volume and has high efficiency as well as high stability which is much better than linear power supply.

4 built in protections:
-current limiting protection(If the preset current is bigger than 9.999A,the setting number will trip automatically),over-temprature protection,voltage overload protection, short-circuit protection
Power-On Delay:
It will avoid boot output voltage overshoot to prevent against burning out of the power supply.

This power supply can not switch between ac and dc.
To avoid burning out the dc power supply, please switch the input to 110V first!

La Crosse Technologies V10-TH

The La Crosse V10-TH Wireless Weather Station (Model No. C84343) is absolutely wonderful. The setup was easy with the Quick Setup Guide provided with the unit. The packaging contains additional support information with the website and phone number if there are questions. I especially liked the daily high low readings and the color on the unit! Tech Instrumentation provided great communication as to the availability of the product and shipping details. If fact, it arrived one day prior to the estimated delivery date. I would absolutely recommend this product and Tech Instrumentation for anyone looking for an indoor/outdoor weather station!


I needed a replacement as my original sensor no longer worked. This one works fine.

Excellent Customer Service!

I can't way enough about the customer service at Tech Instrumentation. I was looking for a hard to find specialty part, which the manufacturer told me would need to be custom made. After calling and speaking with a representative at Tech Instrumentation, the part was located and order was filled, right over the phone. Delivery was prompt, and instrument is working great. Highly recommended company for lab supplies!

Worked great

Put batteries in and worked great
