These equations will reduce the resistance of the external programming resistor, making the impedance into the module trim pin lower for applications in high electrical noise applications. R trim down  100 %  R trim up  100 %  Where desired For example, to trim-up the output voltage of 1.2V module EQW025A0P/P1-V by 5% to 1.26V, Rtrim-up is calculated is as follows: R trim up  100 5  Rtrim The value of the external trim resistor for the optional 1.2V module is only 20% of the value required with the standard trim equations. At 48Vin +/- 2.5V , EQW series modules can be trim down to 20% over the entire temperature range. This allows for margining the unit during manufacturing process if the set point voltage is lower than the standard output voltage. Please consult your local GE field application engineer for additional details. The voltage between the Vo + and terminals must not exceed the minimum output overvoltage protection value shown in the Feature Specifications table. This limit includes any increase in voltage due to remote-sense compensation and output voltage set-point adjustment trim. Although the output voltage can be increased by both the remote sense and by the trim, the maximum increase for the output voltage is not the sum of both. The maximum increase is the larger of either the remote sense or the trim. The amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. When using remote sense and trim, the output voltage of the module can be increased, which at the same output current would increase the power output of the module. Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power Maximum rated power = Vo,set x Io,max .

Page 14 Data Sheet EQW012/020/023/025 Series, Eighth-Brick Power Modules 36 - 75Vdc Input 1.2Vdc to 5Vdc Output 12A to 25A Output Feature Description Continued Overcurrent Protection To provide protection in a fault output overload the module is equipped with internal currentlimiting circuitry, and can endure current limiting continuously. At the instance of current-limit inception, the output current begins to tail-out. When an overcurrent condition exists beyond a few seconds, the module enters a “hiccup” mode of whereby it shuts down and automatically attempts to restart upon cooling. While the fault condition exists, the module will remain in this hiccup mode, and can remain in this mode until the fault is cleared. The unit operates normally once the output current is reduced back into its specified range. Output Over Voltage Protection The output overvoltage protection clamp consists of control circuitry, independent of the primary regulation loop, that monitors the voltage on the output terminals. This control loop has a higher voltage set point than the primary loop See the overvoltage clamp values in the Feature Specifications Table . In a fault condition, the overvoltage clamp ensures that the output voltage does not exceed Vo,ovsd, max. This provides a redundant voltage-control that reduces the risk of output overvoltage. Input Undervoltage Lockout At input voltages below the input undervoltage lockout limit, the module operation is disabled. The module will begin to operate at an input voltage between the undervoltage lockout limit and the minimum operating input voltage. Overtemperature Protection To provide protection under certain fault conditions, the unit is equipped with a thermal shutdown circuit. The unit will shutdown if the thermal reference point Tref Figure 43 , exceeds 125oC typical , but the thermal shutdown is not intended as a guarantee that the unit will survive temperatures beyond its rating. The module will automatically restarts after it cools down. Thermal Considerations The power modules operate in a variety of thermal environments however, sufficient cooling should be provided to help ensure reliable operation. Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel. The thermal reference point, Tref used in the specifications is shown in Figure For reliable operation this temperature should not exceed 115 oC.

Feature Description Continued

Overcurrent Protection

To provide protection in a fault output overload the module is equipped with internal currentlimiting circuitry, and can endure current limiting continuously. At the instance of current-limit inception, the output current begins to tail-out. When an overcurrent condition exists beyond a few seconds, the module enters a “hiccup” mode of whereby it shuts down and automatically attempts to restart upon cooling. While the fault condition exists, the module will remain in this hiccup mode, and can remain in this mode until the fault is cleared. The unit operates normally once the output current is reduced back into its specified range.

Output Over Voltage Protection

The output overvoltage protection clamp consists of control circuitry, independent of the primary regulation loop, that monitors the voltage on the output terminals. This control loop has a higher voltage set point than the primary loop See the overvoltage clamp values in the Feature Specifications Table . In a fault condition, the overvoltage clamp ensures that the output voltage does not exceed Vo,ovsd, max. This provides a redundant voltage-control that reduces the risk of output overvoltage.

Input Undervoltage Lockout

At input voltages below the input undervoltage lockout limit, the module operation is disabled. The module will begin to operate at an input voltage between the undervoltage lockout limit and the minimum operating input voltage.

Overtemperature Protection

To provide protection under certain fault conditions, the unit is equipped with a thermal shutdown circuit. The unit will shutdown if the thermal reference point Tref Figure 43 , exceeds 125oC typical , but the thermal shutdown is not intended as a guarantee that the unit will survive temperatures beyond its rating. The module will automatically restarts after it cools down.

Thermal Considerations

The power modules operate in a variety of thermal environments however, sufficient cooling should be provided to help ensure reliable operation.

Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel.

The thermal reference point, Tref used in the specifications is shown in Figure For reliable
operation this temperature should not exceed 115 oC. The output power of the module should not exceed the rated power for the module Vo, set x Io, max .
