2 / 2 page Model Selection Guide Mechanical Notes: • All dimensions are typical in inches (mm) • Tolerance x.xx = ±0.01 (±0.25) Notes: 1. When measuring output ripple, it is recommended that an external 1.0 µF ceramic capacitor be placed from the +Vout pin to the -Vout pin for single output units and from each output to common for dual output units. For noise sensitive applications, the use of 4.7 µF capacitors will reduce the output ripple.The maximum rms value of the output ripple is 10 mV. 2. Transient recovery is measured to within a 1% error band for a 75-100% load change. 3. The maximum sink current at the on/off pin (pin 4) during a logic low is 100 µA.The maximum allowable leakage current of a switch connected to the on/off pin (Pin 4) at logic high (2.5V to 100V) is 5 µA. If the on/off pin (Pin 4) is left open, the unit operates. If it is grounded, the unit will shut off. 4. No load operation will not damage these units, but they may not meet all spec’s. 5. Dual output units may be connected to provide a 24 VDC or 30 VDC output. To do this, connect the load across the positive (+Vout) and negative (-Vout) outputs and float the output common. 6. The converter should be connected to a low ac-impedance source.An input source with a highly inductive imped- ance may affect the stability of the converter. In applications where the converter output loading is high and input power is supplied over long lines, it may be necessary to use a capacitor on the input to insure start-up. In this case, it is recommended that a low Equivalent Series Resistance (ESR <1.0 at 100 kHz) capacitor be mounted close to the converter.A 33 µF is recommended for 24V input models and a 10 µF for 48V units. 7. It is recommended that a fuse be used on the input of a power supply for protection. See the table above for the correct rating. Heatsink Notes: • Use of the heatsink will extend the units operating temperature range by approximately 10°C. • The heatsink is black anodized aluminum. www.micropowerdirect.com MicroPower Direct We Power Your Success - For Less! 292 Page Street Ste D Stoughton, MA 02072 • TEL: (781) 344-8226 • FAX: (781) 344-8481 • E-Mail: sales@micropowerdirect.com Pin Single Dual Pin Single Dual 1 +Vin +Vin 6 +Vout Comm. 2 -Vin -Vin 7 -Vout -Vout 4 ON/OFF ON/OFF 8 Trim Trim 5 No Pin +Vout Pin Connections Model Number Input Output Over Voltage Protection (VDC) Efficiency (%, Typ) Capacitive Load (µF Max) Fuse Rating Slow-Blow (mA) Voltage (VDC) Current (mA) Voltage (VDC) Current (mA, Max) Current (mA, Min) Nominal Range Full-Load No-Load F2501RW 12 9.0 - 18.0 1,867 40 3.3 5,500 400.0 3.9 81 470 6,000 F2502RW 12 9.0 - 18.0 2,480 40 5.0 5,000 350.0 6.8 84 470 6,000 F2503RW 12 9.0 - 18.0 2,841 40 12.0 2,500 166.0 15.0 88 470 6,000 F2504RW 12 9.0 - 18.0 2,841 40 15.0 2,000 133.0 18.0 88 470 6,000 F2505RW 12 9.0 - 18.0 2,841 40 ±12.0 ±1,250 ±83.0 ±15.0 88 ±220 6,000 F2506RW 12 9.0 - 18.0 2,841 40 ±15.0 ±1,000 ±65.0 ±18.0 88 ±220 6,000 F2511RW 24 18.0 - 36.0 922 20 3.3 5,500 400.0 3.9 82 470 3,000 F2512RW 24 18.0 - 36.0 1,225 20 5.0 5,000 350.0 6.8 85 470 3,000 F2513RW 24 18.0 - 36.0 1,404 20 12.0 2,500 166.0 15.0 89 470 3,000 F2514RW 24 18.0 - 36.0 1,404 20 15.0 2,000 133.0 18.0 89 470 3,000 F2515RW 24 18.0 - 36.0 1,404 20 ±12.0 ±1,250 ±83.0 ±15.0 89 ±220 3,000 F2516RW 24 18.0 - 36.0 1,404 20 ±15.0 ±1,000 ±65.0 ±18.0 89 ±220 3,000 F2521RW 48 36.0 - 75.0 461 10 3.3 5,500 400.0 3.9 82 470 1,500 F2522RW 48 36.0 - 75.0 613 10 5.0 5,000 350.0 6.8 85 470 1,500 F2523RW 48 36.0 - 75.0 702 10 12.0 2,500 166.0 15.0 89 470 1,500 F2524RW 48 36.0 - 75.0 702 10 15.0 2,000 133.0 18.0 89 470 1,500 F2525RW 48 36.0 - 75.0 702 10 ±12.0 ±1,250 ±83.0 ±15.0 89 ±220 1,500 F2526RW 48 36.0 - 75.0 702 10 ±15.0 ±1,000 ±65.0 ±18.0 89 ±220 1,500 Mechanical Dimensions A simple external circuit may be used to adjust the converter output. To adjust the output DOWN, connect a 5%, 3W resistor between the plus output pin and the Vout trim pin. To adjust the output UP, connect a 5%, 3W resistor between the minus output pin and the Vout trim pin. To calculate the correct resistor value use: UP Radj = (33 x Vout) - (30 x Vadj) Vadj - Vout Down Radj = (36.667 x Vout) - (33 x Vout) Vout - Vadj For UP/Down trimming capability, connect a 10 kW potentiometer between the plus and minus outputs with the wiper arm connected to the Vout trim pin.
