Rev. C TECHNICAL DATASHEET JH48S5-150 DESIGN CONSIDERATIONS Under Voltage Lock Out (UVLO) The converter output is disabled until the input voltage exceeds the UVLO turn on limit. The converter will remain on until the input voltage falls below UVLO turn off limit. Over Current Protection The converter is protected from short circuit and over current conditions. During these fault conditions, the converter output will ‘hiccup’. The converter output will recover once the short or over current fault is removed. Over Temperature Protection (OTP) The converter has internal thermal protection that will shut the converter off once the case temperature exceeds the OTP turn off limit. The converter will resume operation when the case temperature has dropped below the OTP turn on limit. Input Filter It is recommended to bypass the +Vin and –Vin pins of the converter with a minimum of 22uF (100V minimum) capacitor. No other bypassing is needed. However, to reduce the input ripple beyond what is seen in Photo 1, larger values of capacitance may be used. Additionally, an inductor may be placed between the source and the previously mentioned capacitor. No inductor should be placed between the capacitor and the input to the converter. Output Filter No additional output capacitor is needed for the power supply to operate. However, to reduce the ripple and noise on the output, additional capacitance may be added. A 100uF Ceramic capacitor may be added across the +Vo and –Vo pins to reduce the ripple and spike noise. Additional capacitance in the form of a tantalum or aluminum electrolytic may also be placed across these pins in order reduce ripple and improve the transient peak-to-peak voltage deviation. Remote Sense To improve the regulation at the load, route the connections from the -RS and the +RS pins to the –Vo and +Vo connections at the load. This will force the converter to regulate the voltage at the load and not at the pins of the converter (refer to Graph 8). If it is not desired to use the Remotes Sense feature, the –RS and +RS pins may be left open or they may be shorted to the -Vo and +Vo pins respectively. Shorting the RS pins to the Vo pins will reduce the voltage drops through the converter pins. Remote ON/OFF The converter has the ability to be remotely turned ON or OFF. The JH series may be ordered Active-High or Active-Low. Active-High means that a logic high at the ON/OFF pin will enable the supply (Figure 2). With Active-High, if the ON/OFF pin is left floating, the supply will be enabled. Active-Low means that a logic low at the ON/OFF pin will enable the supply (Figure 3). With Active-Low, if the ON/OFF pin is left floating, the supply will be disabled. If remote ON/OFF is not used on an Active-Low supply, short the ON/OFF pin to -Vin. Figure 2: Active-High (888) 597-WALL Figure 3: Active-Low www.wallindustries.com 4 WALL INDUSTRIES, INC. TECHNICAL DATASHEET Rev. C JH48S5-150 Output Voltage Trim The output is adjustable from –10% to +20% of the output voltage. To adjust the output voltage down, place a resistor between the TRIM and -RS pins (Figure 4). To adjust the output voltage up, place a resistor between the +RS and TRIM pins (Figure 5). Figure 4: Trim Down Figure 5: Trim Up The value of the TRIM resistor with respect to the desired output voltage Vo trim can be found in Table 2 or derived from the following equation: ( Rup / down = ) 5.11⋅Vo + / − − 5.11 (in kΩ) Vonom − Vo + / − Conversely, Rup + 5.11 Rup Rdown + 5.11 = Vonom ⋅ Rdown + 10.22 Table 2: Trim Resistor Values (all in kΩ) Vo + = Vonom ⋅ Vo − where Vonom = nominal Output Voltage For units with Option E, the trim equations can be derived from the following equations: Rdown = Rup = 11⋅Vo − − 4.965 (in kΩ) 4.965 − Vo − 7.286 ⋅Vo + + 1.225 (in kΩ) 0.2466 ⋅Vo + − 1.225 Note: while decreasing the output voltage, the maximum output current still remains at 30A, and while increasing the output voltage, the output current is reduced to maintain a total output power at 150 W.

Rev. C TECHNICAL DATASHEET JH48S5-150 Paralleling Converters The JH series converters may be paralleled both for redundancy and for higher output current. However, in order to do this, a high-current, low Vf, schottky diode must be placed at the +Vo pin of each supply as shown in Figure 6. To improve sharing, tie the two TRIM pins together. The converters may be trimmed by adding a resistor value from Table 2 from each TRIM pin to ±RS pin, or alternatively, a single resistor of half the value of Table 2 from the common TRIM pins to the common ±RS pins. Figure 6: Paralleling Converters Voltage Measurements To reduce errors caused by voltage drops, all voltage measurements are taken directly at the converter pins. Fusing It is required that the input to the converter be supplied with either a maximum 1.5A rated fuse, or through a current-limited source with a maximum limit of 1.5A. Safety The JH48 series is designed to meet EN60950 requirements for Information Technology Equipment. The isolation provided by the IS48 series is an operational insulation in accordance with EN60950. SELV output reliability is maintained only if the input to the JH48 converter is from a SELV source (888) 597-WALL www.wallindustries.com 6 WALL INDUSTRIES, INC. TECHNICAL DATASHEET Rev.
