The TRACO Power TBA 2-1212 Isolated DC/DC Converters Encapsulated SIP-7, 2W Output 1 (Vdc): 12 is a compact, single-input voltage DC-DC converter measuring 0.46 x 0.48 x 0.59 inches (11.7 x 12.2 x 15 mm). The device converts a wide, 4:1 input voltage range of 9 to 36 VDC into a tightly regulated 12 VDC output, with an efficiency up to 90 percent. The TBA 2-1212 is isolated and produces 2000 mW of output power at an ambient temperature of 40 degrees Celsius without a heatsink. Additionally, the device includes a built-in under-voltage lockout, over-voltage protection, and short-circuit protection for added security.
