The WEV302 thermal solution kit can be used with following laser diode drivers and temperature controllers from Wavelength Electronics: WTCP5V5A, WTC3243, WTC3243HB, WHY5640, WLD3343, WLD3343-2L, WLD3343-3A, WLD3343-3L or WLD3343HB. The controllers operate to 500 mA without any additional heatsinking (assuming 5 V operation). To operate up to 1 A, add the WTW002 thermal washer and the WHS302 heatsink. To operate to the full 2.2 A, add a fan WXC303 (5 V) or WXC304 (12 V). For convenience, a kit with two 0.75" and two 1" screws is available: WXC305. The WEV302 includes the WTW002 thermal washer, the WHS302 heatsink, the WXC305 screw kit, and a +12 V fan WXC304. Two other kits are available: WEV300 (includes thermal washer, heatsink, and screw kit) or WEV301 (includes thermal washer, heatsink, screw kit, and a +5 V fan).
