CUS1000M-24 | TDK-Lambda 1000W Medical / Industrial AC-DC Switching Power Supply
 Product Definition

TDK-Lambda CUS1000M-24 is a 1000W enclosed AC-DC power supply from the CUS-M series. It features medical safety certifications and high power density. It provides fixed 24V output and is not a programmable power supply, designed for DC power supply in medical equipment and precision industrial instruments.

## Core Functions

1. AC-DC Conversion: Converts single-phase AC mains to stable 24V DC output. The output voltage can be fine-adjusted within a narrow range via potentiometer (23.4~25.9V). It is not full-range programmable with 0V starting adjustment.

2. Built-in 5V/2A standby auxiliary power supply for powering mainboard control circuits.

3. Remote On/Off function to enable system-level start and stop control.

4. Comprehensive protections: OVP over-voltage, OCP over-current, OTP over-temperature and short-circuit protection.

5. Variable-speed thermally controlled fan: Low noise at 30~42dBA; low fan speed under light load for noise reduction.

6. Medical-grade isolation with **2×MOPP**. Earth leakage current <250μA, complying with safety requirements for medical devices.

7. Multiple units can be paralleled for higher output current (current sharing supported). Series operation for voltage boosting is not available.

8. High-altitude suitability: Normal operation up to 5000m altitude.
