DS_S48SA05006_06022006 This power module is not internally fused. To achieve optimum safety and system protection, an input line fuse is highly recommended. The safety agencies require a normal-blow fuse with 3A maximum rating to be installed in the ungrounded lead. A lower rated fuse can be used ba...
