myVolts A0505S-1WR2 DC-DC Power Supply Module 4.5-5.5V Input ±5V Output

SKU CH-XPWT-A6T3C

DC-DC module isolates a 4.5-5.5V rail to ±5V at 1500VDC with up to 86% efficiency and an operating range of -40°C to +105°C

  • TypeAT
  • Isolated output protects circuits with 1500VDC isolation
  • Wide 4.5-5.5V input suits variable power sources
  • Dual ±5V rails deliver ±100mA maximum current
  • High efficiency up to 86% reduces heat loss
  • Industrial temperature range -40°C to +105°C ensures reliability

Isolated DC-DC module for board-level power

The myVolts A0505S-1WR2 converts a 4.5-5.5V DC input into a regulated ±5V DC output with 1500VDC isolation. It suits engineers who need a compact SIP or DIP package for embedded systems where input and output grounds must remain separate. The module delivers up to ±100mA per rail with a minimum load of 10mA.

Thermals noise and power draw in normal use

Rated efficiency reaches 86% at full load, with typical figures of 76% to 80% across the operating range. No moving parts are present, so acoustic noise is absent. The unit operates continuously from -40°C to +105°C without derating, making it suitable for industrial environments with wide temperature swings.

Sustained load behaviour rather than short burst

Built-in protection guards against over-current, over-voltage and under-voltage conditions during prolonged operation. Maximum capacitive load is rated at 100µF per output, ensuring stable regulation when driving downstream circuitry. The isolation barrier maintains 1500VDC withstand voltage throughout the temperature range.

Questions about this item

How do I install the A0505S-1WR2 module and what is the step people often get wrong?

Mount the SIP or DIP pins into your board power system with a stable 4.5-5.5V DC input; the step often missed is confirming the input voltage stays within ±10% of nominal so the 1500VDC isolation remains effective.

What maintenance or replacement will the A0505S-1WR2 need later?

No scheduled maintenance is required; if the module ever fails, replace the entire unit because the internal isolation barrier and protection circuits are not serviceable.

What limit appears first when the A0505S-1WR2 runs continuously at full load?

The ±100mA maximum output current is reached first; exceeding it triggers over-current protection and the 76% typical efficiency at full load means noticeable heat rise inside the -40°C to +105°C operating range.
