Full operation over the military temperature range, –55°C to +125°C, makes the MOR Series an ideal choice for military, aerospace, space, and other high reliability applications. In compliance with MIL-STD-704D, the converters will withstand transients of up to 50 volts for up to 120 milliseconds. Use Interpoint’s FME28-461 EMI filter to pass MIL-STD-461C, CE03 requirements. The MOR Series converters incorporate a single-ended forward topology which uses a constant frequency Pulse Width Modulator Crane Aerospace & Electronics, Interpoint Corp. PO Box 97005 • Redmond WA 98073-9705 425.882.3100 • [email protected] www.craneae.com (PWM) current mode control design and switches at 550 kHz, nominal. The converters also provide short circuit protection by restricting the current to 125% of the full load output current. All models offer two inhibits, one referenced to input common and one referenced to output common. A remote sense function is available on single output models. Using the trim function, the MOR Series can provide any output from 2 to 33 VDC. For example, trimming the two 15 volt outputs of the 15 dual (MOR2815D) to 14 volts, and then stacking the outputs will provide a 28 volt output.

Transient range is 40 to 50 V for a maximum of 120 msec. Low voltage lockout prevents the units from operating below approximately 15.5 VDC input voltage to keep system current levels smooth, especially during initialization or re-start operations. All models include a soft-start function to prevent large current draw and minimize overshhoot. CASE AND EXTERNAL INPUT FILTERS Internal 500 V capacitors are connected between the case and input common and between the case and output common.

When using an external input filter it is important that the case of the filter and the case of the converter be connected through as low as an impedance as possible. Direct connection of the baseplates to chassis ground is the best connection. If connected by a single trace, the trace should be as wide as it is long. TRIM Both single and dual output models include a trim function. Output voltage can be trimmed from 60% up to 110% of nominal V out . When trimming up, do not exceed the maximum output power. When trimming down, do not exceed the maximum output current. See Figure 4. On dual models the positive output is regulated and the negative output is transformer coupled (cross-regulated) to the positive output. When trimming the duals, both output voltages will be adjusted equally.

Dual output models with balanced loads operate from no load to full load. For dual models with unbalanced loads, at least 10% of the total output power must be drawn from the positive output at all times, however, the negative output does not require a minimum load. See note 7, cross regulation, under the Electrical Characteristics Tables. Dual outputs may be “stacked” to double the output voltage. See Figure 11.
