The PM400L series of power amplifier modules are intended for incorporation in other electronic equipment such as powered speakers where the end user does not come into direct contact with the output speaker connections. The amplifiers are line powered and provide CSA/UL/VDE isolation from the power line. They also meet FCC class A emissions requirements. The units in the series are:
PM400LA - This module is designed for operation off 110/120VAC power systems such as North America
PM400LE - This module is designed for operation off 220/240VAC power systems such as Europe
PM400LU - This module has a universal supply input and PFC for special applications where power factor correction or a wide input supply is required.
| Input Supply | Line powered |
| Output supplies | +5V, -5V at 100mA each output |
| Frequency Response | 2Hz to 20KHz |
| Noise Level | Less than 10mV RMS |
| Distortion | <0.5% at 400W, 110VAC/220VAC 1KHz |
| Size | 6.8 x 3.8 x 1.5 inches (PM400LA/U)(LWH) |
Both of these power amplifiers are intended for use as general purpose amplifier modules where high power and efficiency are required. They are useful for powered speakers, mobile amplifiers and many other applications.
