3 to 50VDC Digital Two Wire LED Panel Mount Voltmeter Buyer and Importer

We are looking for a DC digital voltmeter, with the following specifications: 1: It should be a two wire model, that measures the voltage on the same two wires that supply it power. 2: The panel cut-out should ideally be smaller than 40X25mm. 3: It must provide at least a 3 to 50VDC reading range. 4: It must have a 3 digit readout with a decimal point after the first two digits (for example: 25.3V) 5: We will need 5 free samples to test, and if they prove satisfactory, we will be ordering 100 to 300 units per month for inclusion in 3 of our products.
