The TEP-75WI Series is a family of isolated high performance DC/DC converter modules with ultra-wide 4:1 input voltage ranges which

come in a rugged, sealed metal case. These converters are suitable for a wide range of applications, but the product is designed par-

ticularly also for industrial applications where often no PCB mounting is possible but the module has to be mounted on a chassis. Four

threaded M3 inserts in the module makes chassis mount or attachment of a heatsink for optimal thermal management very simple.

For easy connection there is also an unique adaptor available with screw terminals. A very high efﬁciency allows an operating temper-

ature up to +60°C with natural convection cooling without power derating. Further features include output voltage trimming, Remote

On/Off and under voltage lockout. The very wide input voltage range and reverse input voltage protection make these converters also

an interesting solution for battery operated systems.

Application Note TEP 75WI Series Output Voltage Adjustment Output voltage is adjustable for 10% trim up or -20% trim down of nominal output voltage by connecting an external resistor between the TRIM pin and either the +SENSE or -SENSE pins. With an external resistor between the TRIM and -SENSE pin, the output voltage set point decreases. With an external resistor between the TRIM and +SENSE pin, the output voltage set point increases. Maximum output deviation is +10% inclusive of remote sense.

Application Note TEP 75WI Series Remote Sense To minimum the effects of distribution losses by regulating the voltage at the Remote Sense pin. The voltage between the SENSE pin and OUTPUT pin must not exceed 10% of Vout, i.e. [ +OUTPUT to –OUTPUT ] – [ +SENSE to –SENSE ] < 10% Vout The voltage between +OUTPUT and –-OUTPUT terminals must not exceed the minimum output overvoltage protection threshold. This limit includes any increase in voltage due to remote sense compensation and trim function.
PAGE 58
Application Note TEP 75WI Series Output Over Current Protection When excessive output currents occur in the system, circuit protection is required on all power supplies. Normally, overload current is maintained at approximately 110~140 percent of rated current for TEP 75WI series. Hiccup-mode is a method of operation in a power supply whose purpose is to protect the power supply from being damaged during an over-current fault condition.
PAGE 59
Application Note TEP 75WI Series Thermal Consideration The power module operates in a variety of thermal environments. However, sufficient cooling should be provided to help ensure reliable operation of the unit. Heat is removed by conduction, convection, and radiation to the surrounding Environment. Proper cooling can be verified by measuring the point as the figure below. The temperature at this location should not exceed 105 C°.

Application Note TEP 75WI Series Remote ON/OFF Control The CTRL pin is controlled DC/DC power module to turn on and off, the user must use a switch to control the logic voltage high or low level of the pin referenced to -INPUT. The switch can be open collector transistor, FET and Photo-Couple. The switch must be capable of sinking up to 1 mA at low-level logic voltage. High-level logic of the CTRL pin signal maximum voltage is allowable leakage current of the switch at 12V is 0.5 mA.
