The PSHDN240 series of AC/DC converters offers 240 watts of power in a 4.92” x 5.12” x 1.97” DIN rail package. This series consists of single output models with a wide input voltage range of either 85-277VAC or 120-390VDC. Features of this series include high efficiency and high reliability, active PFC, and protection against output short circuit, over current, over voltage, and over temperature conditions. This series supports DC OK, AC OK, remote control function, parallel current sharing, and ModBus communication protocol. It also has safety according to ATEX, IECEx, ANSI/ISA 71.04-2013 G3, IEC/EN/UL/BS EN62368, GB4943, IEC/EN/UL61010, EN61558, EN62477, IEC60079, GB3836, and NB/T31017.

Notes & safety
Notes: 1. When the output voltage rises, the total power of the product should not exceed the rated power.
2. For power consumption curve, over current protection mode and short circuit protection, see product characteristic curve.
3. Tip and barrel method is used for ripple and noise test, output parallel 47uF electrolytic capacitor and 0.1uF ceramic capacitor, contact factory for more information.
4. Over temperature protection: put the product into a high temperature box. After the ambient temperature stabilizes, increase the temperature slightly (3°C to 5°C_ and the load remains unchanged. After the product reaches thermal equilibrium, increase the temperature until the product triggers over temperature protection.
5. The power supply has two converters with two different switching frequencies. Intermittent operation mode will be entered in light load or no load.
6. When multiple prototypes are working in uniform current, the output voltage deviation of each prototype working separately shall not exceed 100mV.
7. Room temperature derating of 5°C/1000m is needed for operating altitude greater than 2000m.
8. In order to improve the efficiency at high input voltage, there will be audible noise generated, but it does not affect product performance and reliability.
9. Customization is available, please contact factory.
10. Product customization is available. Please contact factory.
11. The out case needs to be connected to PE of system when the terminal equipment is operating.
12. Key to adjust Δ key for voltage increase ▽ key for voltage decrease
13. Products classified to ISO14001 and related environmental laws and regulations and should be handled by qualified units.
*Due to advances in technology, specifications subject to change without notice.
Safety Approvals: Design refers to IEC/EN/UL/BS EN62368-1, IEC/EN/UL61010-1, GB4943.1, EN61558-1, EN62477-1, IEC60079-0, IEC60079-7, IEC60079-15, GB3836.1, NB/T31017, ANSI/ISA 71.04-2013
