| Model and output configuration |
DPB09B-15; isolated, regulated dual-output DC/DC converter in an industry-standard SIP8 package. |
| Output voltage |
±15 V DC relative to Common. Simultaneous rails: +15 V and −15 V. |
| Output current range |
0–300 mA in magnitude on each rail. No minimum load is required. |
| Output power and current limit |
9 W total converter rating, subject to the stated current limits and thermal derating. Both rails share this total rating; rounded per-rail current figures do not increase it. |
| Nominal input and operating range |
24 V DC nominal; 18–36 V DC operating range. 2:1 input-range family. |
| Input current |
15 mA at no load; 431 mA at full load under the general measurement conditions. |
| Typical efficiency |
87% at nominal input and rated load under the general measurement conditions. |
| Maximum capacitive load |
47 µF for each output. |
| Input filter and recommended fuse |
Internal input capacitor; a 1 A slow-blow input fuse is recommended. |
| Output voltage accuracy |
±1.5%. |
| Ripple and noise |
100 mVp-p. Measured at 20 MHz using a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors. |
| Line regulation |
0.5%, measured from low line to high line at rated load. |
| Load regulation |
±0.5%, measured from 10% to 100% rated load. |
| Switching frequency |
400 kHz minimum. |
| General measurement conditions |
Unless otherwise specified: nominal 24 V input, rated load, 25°C and 70% RH ambient. |
| Series efficiency capability |
The SPB09/DPB09 family offers efficiency up to 89% across its models. Use the selected model’s typical value above. |
| Series output option |
The series lists an optional 9 V output version. Confirm the complete ordering code and model-specific ratings with MEAN WELL; this listing retains the selected output stated above. |
