DVMN28 HIGH RELIABILITY EMI FILTER AND INPUT ATTENUATOR DESCRIPTION FEATURES The DVMN28 is a combined EMI filter and voltage spike protection module that is operable over a wide temperature range (-55 °C to +100 °C) with no power derating. The DVMN28 EMI filter works with VPT/Delta’s DV200 series DC-DC converters to meet the surge requirements of MIL-STD-704A, B, C, and D with up to 250 watts of output power. These devices also reduce the reflected noise of the DC-DC converters to meet MIL-STD-461C CE03 and MIL-STD-461D CE102 limits. The DVMN28 filter also protects the DC-DC converters against the voltage spikes specified in MIL-STD-461C CS06 and conducted susceptibility in MIL-STD-461C CS01 and CS02. • • • • • • • • • • • These filters are designed and manufactured in a facility qualified to ISO9001 and certified to MIL-PRF38534 and MIL-STD-883. • High Reliability 250 Watt Output Power 50 dB Minimum Attenuation at 500 kHz Soft Start Under Voltage Lockout Clamps Output Voltage to 58 Volts Maximum Standard Quarter-Brick Size Custom Versions Available Additional Environmental Screening Available Meets MIL-STD-704A, B, C, and D Surge Limits Designed to meet MIL-STD-461C CE03 and MIL-STD-461D CE102 and DEF STAN 59-41 and 61-5 EMC Requirements Protects Against Conducted Susceptibility Specified in MIL-STD-461C, CS01 and CS02 and Against Voltage Spikes Specified in MILSTD-461C CS06 Figure 1 – DVMN28 EMI Filter (Not To Scale) 15005DSC 11314 4th Avenue West, Suite 206 Everett, WA 98204 http://www.vpt-inc.com Sales Information: Phone: (425) 353-3010 Fax: (425) 353-4030 E-mail: [email protected] 1 DVMN28 SPECIFICATIONS (TCASE = -55°C to +100°C, VIN = +28V ± 5%, Full Load, Unless Otherwise Specified) ABSOLUTE MAXIMUM RATINGS Input Voltage (Continuous) Input Voltage (Transient, up to 10µs) Output Current1 Weight (Maximum) Parameter 50 VDC 600 Volts 14 Amps 75 Grams Power Dissipation (Continuous) Storage Temperature Lead Solder Temperature (10 seconds) 12 Watts -65°C to +135°C 300°C DVMN28 Conditions Units Min Typ Max With load 16 28 50 V 5 ms, RS = 0.5 Ω -40 - 70 V STATIC Continuous INPUT 2 Voltage Transient Transient 3 Transient Current OUTPUT Voltage - - 110 V - - 600 V No Load - - 12 mA Inhibited - - 2.0 mA Continuous 1,4 Power Current 50 ms, RS = 0.5 Ω 10 µs, RS = 50 Ω VOUT = VIN – (IIN x RDC) Continuous 1,4 Continuous 250 W 14 A 16 V Open Circuit - Inhibited 0 - 0.8 V Inhibit Pin Voltage = 0 to 0.8 V - - -300 µA UNDERVOLTAGE LOCKOUT 7 - 14 V OUTPUT CLAMP VOLTAGE 51 - 55 V INHIBIT PIN VOLTAGE 2 INHIBIT PIN CURRENT 2 14 V DC RESISTANCE Continuous 60 mΩ POWER DISSIPATION Continuous - - 12 W NOISE REJECTION f = 500 kHz 50 60 - dB Pin to Case - 85 - nF 100 - - MΩ - 2052 - kHrs CAPACITANCE 2 ISOLATION Any Pin to Case, 500 VDC MTBF (MIL-HDBK-217F) GB @ TC = 55°C Notes: 15005DSC 1.
